Abstract

High-field magnetization measurements have been preformed on a single crystal sample of the pyrochlore compound Gd₂Ti₂O ₇ using a pulse magnet in conjunction with a dilution refrigerator. The magnetization curve at 0.3 K reveals two magnetic phase transitions when the magnetic field is applied along b [111]. At temperatures slightly above T _N, a magnetization plateau appears around 5 T and the magnetization increases again from about 15 T with a convex curvature. It is considered that this crossover is due to a competition among thermal fluctuations, short-range antiferromagnetic ordering and geometrical frustration.
