Direct Imaging of Current-Induced Antiferromagnetic Switching Revealing a Pure Thermomagnetoelastic Switching Mechanism in NiO

Hendrik Meer et al.

Summary: Researchers have unraveled the mechanism of current-induced magnetic switching in insulating antiferromagnet/heavy metal systems using concurrent transport and magneto-optical measurements. Different final states of the switching in specially engineered NiO/Pt bilayers devices were observed with different electrical pulsing and device geometries, attributed to the thermomagnetoelastic switching mechanism combined with thermal excitations. This noncontact mechanism provides a potential explanation for previously reported contradicting observations of switching final state attributed to spin-orbit torque mechanisms.

Ultrafast spin current generated from an antiferromagnet

Hongsong Qiu et al.

Summary: Antiferromagnets (AFMs) have the potential to push spintronic devices to terahertz range for high-speed processing, but their insensitivity to magnetic fields makes spin current manipulation difficult. By optically generating ultrafast spin currents in AFM/HM heterostructures, a new avenue for fundamental research into antiferromagnetism and AFM spintronic devices has been opened.

Effective strain manipulation of the antiferromagnetic state of polycrystalline NiO

A. Barra et al.

Summary: The study reports the detection of the average Neel vector orientation in polycrystalline NiO via spin Hall magnetoresistance (SMR), and reduces the critical magnetic field required to reach a saturation of the SMR signal by applying strain through a piezo-electric substrate. The results show that polycrystalline NiO exhibits a positive sign of the in-plane magnetostriction. This method of anisotropy-tuning provides an energy-efficient, on-chip alternative to manipulate a polycrystalline antiferromagnet's magnetic state.

Identification of Neel Vector Orientation in Antiferromagnetic Domains Switched by Currents in NiO/Pt Thin Films

C. Schmitt et al.

Summary: This study focuses on the electrical manipulation of antiferromagnetic NiO/Pt thin films, demonstrating switching between different domains and quantifying the magnetoelastic coupling coefficient. The findings are crucial for understanding current-induced switching in antiferromagnets and for the design and utilization of such devices in spintronic applications.

Linear and nonlinear spin dynamics in multi-domain magnetoelastic antiferromagnets

O. Gomonay et al.

Summary: This study focuses on the dynamics of domain walls in anti-ferromagnetic materials in the presence of magnetoelasticity, showing that it affects both equilibrium magnetic structure and dynamical properties. Experimental results are compared with model outputs, confirming the significant impact of domain walls on optically driven ultrafast nonlinear spin dynamics.
