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…

Enhancement of the irreversibility field by carbon substitution in single crystal MgB $_{2}$

E. Ohmichi, T. Masui, S. Lee +2

We report the detailed study of the irreversibility field {\hirr} of single crystals of Mg(B $_{1 - x}$ C $_{x}$ ) $_{2}$ ( $x$ =0, 2, 3.5, 5 and 7%) in strong magnetic fields of up to 40 T.…
