Superconductivity enhancement in polar metal regions of SrBaTiO and SrCaTiO revealed by the systematic Nb doping
Yasuhide Tomioka, Naoki Shirakawa, Isao H. Inoue
Two different ferroelectric materials, SrBaTiO and SrCaTiO, can be turned into polar metals with broken centrosymmetry via electron do…
Hill plot focusing on Ce compounds with high magnetic-ordering-temperatures and consequent study of Ce2AuP3
Junya Miyahara, Naoki Shirakawa, Yuta Setoguchi +3
Hill plot is a well-known criterion of the f-electron element interatomic threshold-distance separating the nonmagnetic state from the magnetic one in actinides or lanthanides. We…
Optical, transport and magnetic properties of new compound CeCd3P3
Shohei Higuchi, Yuki Noshima, Naoki Shirakawa +2
We have found that CeCdP crystallizes into a hexagonal ScAlC-type structure. The optical, transport and magnetic properties of CeCdP were invest…
Pressure Effects on Superconducting Properties of the BiS2-Based Superconductor Bi2(O,F)S2
Tomoyuki Okada, Hiraku Ogino, Jun-ichi Shimoyama +5
Pressure effects on a recently discovered BiS2-based superconductor Bi2(O,F)S2 (Tc = 5.1 K) were examined via two different methods; high pressure resistivity measurement and high…
Uniaxial-Pressure induced Ferromagnetism of Enhanced Paramagnetic Sr3Ru2O7
Shin-Ichi Ikeda, Naoki Shirakawa, Takashi Yanagisawa +5
We report a uniaxial pressure-dependence of magnetism in layered perovskite strontium ruthenate Sr3Ru2O7. By applying a relatively small uniaxial pressure, greater than 0.1 GPa nor…
An Improved Method for Obtaining Single-Phase Sr2MoO4 under Controlled Ultra-low Oxygen Partial Pressure
Naoki Shirakawa, Shin-Ichi Ikeda, Hirofumi Matsuhata +1
We investigated a method for obtaining a sintered bulk sample of single-phase Sr2MoO4, which has recently increased in importance due to its similarities to superconducting Sr2RuO4…
Orbital-Degenerate Paramagnetic Metal Sr2MoO4: An Electronic Analogue to Sr2RuO4
Shin-Ichi Ikeda, Naoki Shirakawa, Hiroshi Bando +1
We present the first systematic study on polycrystalline Sr2MoO4 as an electronic analogue to the spin-triplet superconductor Sr2RuO4. The Pauli paramagnetic susceptibility and met…
