Summary: Real-space magnetic imaging and anisotropic magnetoresistance studies on dipolar skyrmions were conducted. The study found that the anisotropic magnetoresistance of skyrmions is proportional to the skyrmion count and independent of the helicity. This research promotes read-out operations in skyrmion-based spintronic devices.

Summary: We report the dynamics of skyrmion bubbles driven by spin-transfer torque in achiral ferromagnetic nanostripes using micromagnetic simulations. The coherent motion of skyrmion bubbles in the nanostripe can be realized by increasing the quality factor, which has potential applications in future spintronic device designs.

Summary: This study presents the formation of biskyrmion bubbles mediated by emergent monopoles through micromagnetic simulations. It is found that biskyrmion bubbles and trivial bubbles have a unified three-dimensional structure, and the two-dimensional topological property of biskyrmions is dominated by the relative position of the intrinsic emergent monopole-antimonopole pair. Biskyrmion bubbles can be transformed from trivial bubbles through the motion of emergent monopoles in confined geometry, paving the way for the development of devices.

Summary: This study reports the finding of a tunable skyrmion lattice that can be stabilized at room temperature in a centrosymmetric kagome ferromagnet Mn4Ga2Sn using Lorentz transmission electron microscopy. The study demonstrates the controlled switching between topological skyrmions and non-topological type-II magnetic bubbles and identifies the topological skyrmions as the energetically most stable magnetic objects in centrosymmetric hexagonal magnets.

Summary: The formation of topological spin structures in the 2D van der Waals magnet Fe5GeTe2 at room temperature is investigated. Skyrmionic magnetic bubbles are observed without preferred chirality, indicating centrosymmetry. The results show that topological spin structures can be stabilized even at room temperature in centrosymmetric van der Waals magnets.

Summary: The domain structure of thin Nd2Fe14B lamellae is studied in this paper. Magnetic bubbles with a minimum diameter of 74 nm were observed at room temperature, approaching the range of magnetic skyrmions. Both the stripe domain width and the bubble size are dependent on the thickness. Moreover, a kind of bubble combining bubbles with opposite helicity was observed below the spin-reorientation transition temperature. The study reveals Nd2Fe14B to be a good candidate for high-density magnetic bubble-based memory.

Summary: Magnetic skyrmions have attracted significant research interest since their discovery a decade ago, due to their non-trivial real-space topology and potential technological applications. However, the utilization of skyrmions in spintronic devices has not been achieved yet, mainly because of shortcomings in their current-driven motion. Additionally, beyond skyrmions, there are emerging trends in the field of topological spin textures.

Summary: This study used differential phase contrast scanning transmission electron microscopy to investigate nanoscale magnetic objects in Kagome ferromagnet Fe3Sn2 nanostructures, revealing that these magnetic objects can be attributed to the integral magnetizations of two types of complex 3D magnetic bubbles with depth-modulated spin twisting. While magnetic configurations obtained using high-resolution TEM are generally considered as two-dimensional, the results suggest the importance of the integral magnetizations of underestimated 3D magnetic structures in 2D TEM magnetic characterizations.

Summary: Magnetic skyrmions are attractive for next-generation spintronic devices due to their stability, small size, and ease of manipulation with spin torques. An all-electrical approach is necessary to nucleate, propagate, and detect skyrmions for read/write operations. This review discusses the basic concepts of magnetic skyrmions, recent results on their electrical behaviors, and future research perspectives in this field.

Summary: Magnetic skyrmions, as topological swirling spin textures, have attracted much attention in spintronics due to their robustness rooted in their topological nature. This study presents a method to generate skyrmions by driving stripe instability, regardless of other material parameters, and applicable to generic magnetic films with perpendicular magnetic anisotropy. The work will facilitate the development of skyrmion-based devices by offering a general method for controlling a large skyrmion population.

Summary: In this study, first and second-order antiskyrmions were stabilized in a new class of materials through the use of magnetic dipole-dipole interaction, providing important insights for spintronic devices. These different spin objects are primarily stabilized by the dipolar interaction, demonstrating considerable technological promise for antiskyrmions in magnetically engineered materials.

Summary: This study investigates the dynamics of skyrmion nucleation and manipulation using Fe3Sn2 and Lorentz transmission electron microscopy. The results reveal that the rotatable anisotropy and thickness dependence are critical factors for skyrmion formation in response to external in-plane fields. It is also shown that the helicity of skyrmions can be controlled through this dynamic process.

Summary: The ability to switch the topological magnetic charge Q in a controlled way by electrical methods allows for flexible manipulation of electromagnetic behavior in future spintronic devices. The study reports room-temperature current-controlled topological magnetic transformations in a kagome crystal Fe3Sn2, showing reproducible and reversible skyrmion-bubble and skyrmion-stripe transformations achieved by tuning the density of nanosecond pulsed current of the order of approximately 10(10) A m(-2). Numerical simulations suggest that spin-transfer torque combined with Joule thermal heating effects determine the current-induced topological magnetic transformations.

Summary: The concept of Skyrmion, originally proposed in particle physics, has found a fertile field for its applicability in magnetic skyrmions realized in helimagnetic materials. These magnetic topological defects show promising properties for future application in spintronics, with extraordinary metastability and low electric current excitation. The review also covers the emergence of other magnetic topological defects and their interplay with skyrmions.
