Magnetic Generation and Switching of Topological Quantum Phases in a Trivial Semimetal α-EuP3

Alex Hiro Mayo et al.

Summary: This study investigates the magnetic-field-induced switching of band topology in alpha-EuP3. The results show that a giant anomalous Hall effect signal emerges when the magnetic field is applied perpendicular to the monoclinic structure's single mirror plane. On the other hand, applying the magnetic field along the interlayer direction leads to a pronounced negative longitudinal magnetoresistance. The researchers found that these anomalies are manifestations of two distinct topological phases: topological nodal-line and Weyl semimetals.

Anomalous transport due to Weyl fermions in the chiral antiferromagnets Mn3X, X=Sn, Ge

Taishi Chen et al.

Summary: The recent discoveries of large zero-field Hall and Nernst effects in antiferromagnets Mn3X (X=Sn, Ge) are considered fingerprints of magnetic Weyl nodes near the Fermi energy, highlighting the importance of magnetic topological states in condensed matter research. This review combines previous reports with new transport measurements on high-quality Mn3Sn and Mn3Ge single crystals, identifying magnetotransport signatures specific to chiral anomalies and planar Hall effect, suggesting the essential role of magnetic Weyl fermions in producing large transverse responses in the absence of magnetization.

Above-ordering-temperature large anomalous Hall effect in a triangular-lattice magnetic semiconductor

Masaki Uchida et al.

Summary: The study of the magnetic semiconductor EuAs revealed a new mechanism for inducing large anomalous Hall effect (AHE) in magnetic semiconductors through spin cluster scattering. This suggests potential for developing a field targeting diluted carriers strongly coupled to noncoplanar spin structures.

Experimental perspective on three-dimensional topological semimetals

B. Q. Lv et al.

Summary: Topological semimetals are characterized by bulk band crossings, which have led to increased research activities in the field due to precise theoretical predictions, well-controlled material synthesis, and advanced characterization techniques. The distinct features of these materials include dimensionality, degeneracy, slope and order of band dispersion, topological invariants, and crystallographic symmetries that stabilize band crossings. Additionally, the unique properties of various topological semimetal phases, such as nontrivial surface states and transport responses, have been reviewed.

Quantum transport observed in films of the magnetic topological semimetal EuSb2

Mizuki Ohno et al.

Summary: We report the fabrication of EuSb2 single-crystalline films and investigation of their quantum transport. The first-principles calculations reveal that EuSb2 is a magnetic topological nodal-line semimetal protected by nonsymmorphic symmetry. The observed Shubnikov-de Haas oscillations with multiple frequency components suggest the presence of small effective masses and two-dimensional field-angle dependence, indicating possible contributions of surface states even in a 250 nm thick film. This finding of a high-mobility magnetic topological semimetal will stimulate further research in exotic quantum transport phenomena by manipulating magnetic order in topological semimetal films.
