Abstract

We studied the magnetic state of pyrochlore Gd2Mo2O7 by pressure-dependent magnetization M(H) and magnetic relaxation measurements up to 16 kbar. The ferromagnetic saturation behavior seen in the M(H) curve was substantially weakened by applying pressure and, at the same time, hysteresis behavior in the magnetization becomes pronounced with pressure. Relaxation in the magnetization, although absent at ambient pressure, emerges upon and increases with pressures. These findings of the suppression of the ferromagnetism and the appearance of a metastable spin glass phase is consistent with the previous results of rare-earth substitution studies.
