LiMn 2 O 4 spinel exhibits spin-glass behavior below 25 K. A cusp in the ac susceptibility appears at 25 K, below which the susceptibility increases with decreasing frequency. The dc magnetization shows irreversibility, and relaxation of remanent magnetization is seen on the macroscopic time scale. The randomness and frustration necessary for spin-glass behavior are explained in a manner compatible with the cation and charge ordering present in this material.
