Abstract
We observed a few magnetic relaxation phenomena in a LuFeMgO4 single c rystal, that is, the difference in the magnetization between field-coo led and zero-field-cooled specimens, the appearance of thermoremanent magnetization, and the frequency dependence of the cusp temperature of AC susceptibility. The observed relaxation was interpreted in terms o f thermal fluctuations and freezing of the magnetic clusters which are supposed to exist in this substance.
