Abstract

The magnetization in a lightly doped (formula presented) (formula presented) single crystal was measured. Spin-flop transition was clearly observed in the hole-doped antiferromagnetically ordered state under increasing magnetic fields perpendicular to the (formula presented) plane. In the spin-glass phase below 25 K, the spin-flop transition becomes broad but the step in the magnetization curve associated with the transition remains finite at the lowest temperature. We show in this report that, at low temperature, the homogeneous antiferromagnetic order is disturbed by the redistribution of holes, and that the spatial variance of the local hole concentration around (formula presented) increases.
