• 論文の詳細を見る

• The anisotropy of the upper critical field H.. has been measured at ambientpressure on a layered organic superconductor /7-(BEDT-TTF').1. both in the statesbefore and after annealing at 109 K for 120 hours. By annealing, the critical temperalure T. increases from 1.4 to 2.08 K, while the H...,.... increascs and the anisotropy,H.z,..../H...,g..., decreases. The angular dependeutces of H.. for both states are ex-plained in terms of the effective mass model. It is clarified that the enhanced T. whichis ascribed to the annealing-induced configurational orderings of ethylene groups isclosely related to the enhanced effective mass in the basal plaune./7-(BEDT-TTF).1, critical field anisotropy
