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.

A-type antiferromagnetic order in semiconducting EuMg2Sb2 single crystals

Santanu Pakhira et al.

Summary: In this study, the crystallographic, magnetic, and electronic properties of EuMg2Sb2 were investigated. It was found that EuMg2Sb2 exhibits narrow-gap semiconductor behavior, activated behavior with intrinsic conductivity, and antiferromagnetic ordering. The reorientation of Eu moments within the trigonal antiferromagnetic domains was also observed at low temperatures.

Giant nonlinear anomalous Hall effect induced by spin-dependent band structure evolution

Xiangyu Cao et al.

Summary: The research discovered that a giant nonlinear anomalous Hall effect can be induced by magnetic-field-induced Lifshitz transitions in the spin-dependent band structure of EuCd2As2. These results not only provide an ideal platform for Berry curvature engineering but also reveal a general effect that may be applicable to other material systems.

Magnetic and electronic structures of antiferromagnetic topological material candidate EuMg2Bi2

Madalynn Marshall et al.

Summary: EuMg2Bi2 has been investigated as an antiferromagnetic (AFM) topological semimetal candidate. The high-quality single crystals grown via a Bi flux were found to exhibit interesting electronic behavior potentially influenced by competing antiferromagnetic and ferromagnetic interactions, consistent with the calculated magnetic structure.

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.

Unconventional Transverse Transport above and below the Magnetic Transition Temperature in Weyl Semimetal EuCd2As2

Y. Xu et al.

Summary: Research on the magnetic Weyl semimetal EuCd2As2 reveals unconventional transverse transport phenomena above and below its magnetic transition temperature, indicating significant Berry curvature and unique transport properties; in the antiferromagnetic phase, the transport properties of the material evolve differently with temperature and magnetic field compared to the paramagnetic phase, suggesting different origins.

High performance Wannier interpolation of Berry curvature and related quantities with WannierBerri code

Stepan S. Tsirkin

Summary: Wannier interpolation is a powerful tool for performing Brillouin zone integrals over dense grids of k points, but more complex physical problems and materials create numerical challenges. This article presents methods to significantly boost the speed of Wannier interpolation, such as combining fast and slow Fourier transforms and using explicit symmetries. These methods have been implemented in the Python code WannierBerri.

Dirac semimetal phase and switching of band inversion in XMg2Bi2 (X = Ba and Sr)

Daichi Takane et al.

Summary: Topological Dirac semimetals (TDSs) present unique physical properties compared to topological insulators, but existing TDSs face challenges such as high reactivity and difficulty in controlling topological phases. The ternary compound BaMg2Bi2 is identified as a TDS with a simple Dirac-band crossing, while SrMg2Bi2 is found to be an ordinary insulator due to reduced spin-orbit coupling. The XMg2Bi2 (X = Sr, Ba, etc.) platform provides a useful tool for studying the interplay among crystal symmetry, spin-orbit coupling, and topological phase transitions in TDSs.
