Abstract
We reported a systematic change in the average magnetic relaxation rate. af ter the application and removal of a 5 T magnetic field, in a polycrystalli ne sample of La0.5Ca0.5MnO3. Magnetic relaxation measurements and magnetiza tion versus field curves were taken from 10 to 160 K. The long time behavio r of the relaxation curves was approximately logarithmic in all cases.
