摘要：
We have carried out a B-11 NMR experiment on a single crystal of Ce0.75La0.25B6 in order to elucidate the nature of phase IV. The NMR spectrum undergoes an appreciable broadening by an internal magnetic field as T is lowered in phase IV. Also, the nuclear spin-lattice relaxation rate, 1/T-1, exhibits a sharp peak around 1.7 K which is close to the phase I-IV transition point, originating from critical magnetic fluctuation towards a magnetic phase transition. These obtained results support the view that phase IV is considered to be a kind of magnetically ordered state. (C) 2002 Elsevier Science B.V. All rights reserved.
