- 論文の詳細を見る
The Knight shift (K ) and the spin-lattice relaxation rate (1 / T3 ) at the V site of CaV3 05 h avebeen measured by means of the pulsed-NMR technique in order to investigate the magneticproperties. By analyzing the tenaperature dependence of the spin susceptibility extracted fromthe Knight shift, it was clarified for the first time that the ground state of the spin system inCaVzO5 is a spin singlet state. Moreover, the energy gap between the ground state and theexcited state was estimated to be about 5OOK from the activation-like behavior of X and l/'Z'l.These results clearly indicate the existence of the spin gap in this material.
