Phase diagram of CeRuPO under pressure investigated by P-NMR - Comparison between CeRuPO under pressure and the Ce(RuFe)PO system -
Shunsaku Kitagawa, Hisashi Kotegawa, Hideki Tou +3
We have performed P-NMR measurements on single-crystalline CeRuPO under pressure in order to understand the variation in magnetic character against pressure. The NMR spectra…
Superconductivity of 2.2 K under Pressure in Helimagnet CrAs
Hisashi Kotegawa, Shingo Nakahara, Hideki Tou +1
We report resistivity measurements of the helimagnet CrAs under pressures. The helimagnetic transition with T_N ~ 265 K at ambient pressure is completely suppressed above a critica…
Detection of an Unconventional Superconducting Phase in the Vicinity of the Strong First-Order Magnetic Transition in CrAs Using ^75As-Nuclear Quadrupole Resonance
Hisashi Kotegawa, Shingo Nakahara, Rui Akamatsu +3
Pressure-induced superconductivity was recently discovered in the binary helimagnet CrAs. We report the results of measurements of nuclear quadrupole resonance for CrAs under press…
Strong Suppression of Coherence Effect and Appearance of Pseudogap in Layered Nitride Superconductor Li_xZrNCl: ^91Zr- and ^15N- NMR Studies
Hisashi Kotegawa, Satoru Oshiro, Yuki Shimizu +5
We present NMR measurements of the layered nitride superconductor Li_xZrNCl. The nuclear spin-lattice relaxation rate, 1/T_1, shows that the coherence peak is strongly suppressed i…
