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…
Pressure-induced volumetric negative thermal expansion in CoZr2 superconductor
Yuto Watanabe, Hiroto Arima, Saori Kawaguchi-Imada +10
We investigate the thermal expansion and superconducting properties of a CuAl2-type (tetragonal) superconductor CoZr2 under high pressures. We perform high-pressure synchrotron X-r…
Superconductivity at 52 K in hydrogen-substituted LaFeAsO1-xHx under high pressure
Hiroki Takahashi, Hideto Soeda, Muga Nukii +6
The 1111-type iron-based superconductor LnFeAsO1-xFx (Ln stands for lanthanide) is the first material with a Tc above 50 K, other than cuprate superconductors. Electron doping into…
Anomalous He-Gas High-Pressure Studies on Superconducting LaO1-xFxFeAs
W. Bi, H. B. Banks, J. S. Schilling +5
AC susceptibility measurements have been carried out on superconducting LaO1-xFxFeAs for x=0.07 and 0.14 under He-gas pressures to about 0.8 GPa. Not only do the measured values of…
Pressure-induced superconductivity in Iron pnictide compound SrFe2As2
K. Igawa, H. Okada, H. Takahashi +6
Electrical resistivity under high pressure have been measured on nominally pure SrFe2As2 up to 14 GPa. The resistivity drop appeared with increasing pressure, and we clearly observ…
