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…

Structural Phase Transition in CeMnSi under Pressure and Comparative Structural Properties of MnSi ( = La, Ce, Pr, Nd)
Yukihiro Kawamura, Sae Nishiyama, Jun-ichi Hayashi +3
Powder X-ray diffraction experiments under pressure up to 10 GPa were performed on tetragonal CeFeSi-type MnSi ( = La, Ce, Pr, Nd). A structural phase transition was ob…
