摘要：

We have carried out In-115 nuclear quadrupole resonance (NQR) measurements of the antiferromagnetic (AF) dense-Rondo compound CeIn3 (T-N = 10 K) under pressure. In the AF ordered state, a small internal field of about 6 kOe (1.6 K) appears in the direction parallel to the respective Ce-In planes. The non-vanishing In-115 internal field means that the Ce magnetic moments orient perpendicular to the (1 1 1) plane. With applied pressure, the internal field decreases gradually and disappears above 24.4 kbar. The nuclear spin-lattice relaxation rate T-1(-1) is nearly temperature independent in the paramagnetic state and is strongly suppressed with increasing pressure. Fermi liquid behavior was observed below 10 K at 27.4 kbar. (C) 2000 Elsevier Science B.V. All rights reserved.
