Abstract

We present a detailed study of magnetic properties of antiperovsite compound Mn₃Cu_0.7Ga_0.3N. Ac susceptibility measurements show a peak around "freezing temperature" (T _f), with the peak position shifting as a function of the driving frequency f and magnetic field H. Magnetic relaxation measurements show a slow decay of the remanent magnetization with time below T_f. These findings consistently demonstrate the existence of spin-glass states in Mn ₃Cu_0.7Ga_0.3N. The behavior may be attributed to either a small amount of disorder, arising from the random occupation of 1a sites in the space group Pm-3m by mixed Cu/Ga atoms, or the common frustration, or both.
