Superconducting fluctuation in FeSe investigated by precise torque magnetometry
Hideyuki Takahashi, Fuyuki Nabeshima, Ryo Ogawa +3
We investigated the superconducting fluctuation in FeSe, which is assumed to be located in the BCS--BEC crossover region, via magnetic torque measurements. In our method, the absol…

Force-detected high-frequency electron spin resonance spectroscopy using magnet-mounted nanomembrane: robust detection of thermal magnetization modulation
Hideyuki Takahashi, Tsubasa Okamoto, Kento Ishimura +3
In this study, we report a conceptually novel broadband high-frequency electron spin resonance (HFESR) spectroscopic technique. In contrast to the ordinary force-detected ESR techn…

Enhancement of the irreversibility field by carbon substitution in single crystal MgB
E. Ohmichi, T. Masui, S. Lee +2
We report the detailed study of the irreversibility field {\hirr} of single crystals of Mg(BC) (=0, 2, 3.5, 5 and 7%) in strong magnetic fields of up to 40 T.…
