Pressure Effects on CeMnSi: Evolution of Ce 4f and Mn 3d Electronic States and Negative Thermal Expansion
Sae Nishiyama, Haruka Mima, Jun-ichi Hayashi +6
We investigated pressure effects on the nontrivial heavy-fermion antiferromagnet CeMnSi by means of electrical resistivity and powder X-ray diffraction. With increasing pressure, t…

Large spontaneous Hall effect arising from collinear antiferromagnetism in CePtGe
Hayata Matsuda, Ruo Hibino, Chihiro Tabata +9
The spontaneous Hall effect, corresponding to a zero-field anomalous Hall effect (AHE), is induced by symmetry breaking associated with ferromagnetism. Studies in recent years, how…

Spontaneous Anomalous Hall Effect at Room Temperature in Antiferromagnetic Material NbMnAs
Yuki Arai, Junichi Hayashi, Keiki Takeda +4
Recent studies have shown that certain antiferromagnetic (AFM) materials with the same symmetry breaking as ferromagnets can generate sufficiently large ferromagnetic (FM) response…
