概要

• 論文の詳細を見る

• The NMR shift and the ntrclear spin-lattice relaxation rate (l/V'l) were meastrred at the Vsites in the two-dimensional compotmnd CaV.jOg. The NMR shif't becomes a positive constantbelow x15 K, indicating that the intrinsic spin susceptibility vanishes at low tetnperatvtres. Theactivated T dependence of I/Tn has revealed the dynamical spin gap ,5n x 104 K, which israther smaller than the static spin gap determined from the susceptibility A3 x 135 K.
