• 論文の詳細を見る

• An upper critical field measurement in the recently discovered ambient pressureorganic superconductor (BEDT-TTF).Cu(NCS). (7'.= 10.4 K) is reported. Three- totwo-dimensional crossover behaviour is observed in the temperature dependence ofthe parallel critical field. The anisotropy of the coherence length near T., 4./ <.=, isabout 19 and<:,=(0) is smaller than the lattice spacing along the *'-axis. An unusualtemperature dependence of the perpendicular critical field is observed far below T.. Itis confirmed that deuterated salt is also an ambient pressure superconductor with aslightly higher T. (11 K).[organic superconductor, BEDT-TTF salt, critical field, critical temperature, lg coherence length, experiment.]
