Anomalies in the Relaxation of Small Magnetic Particles at Very Low Temperatures

R. Sappey, E. Vincent, J. Hammann +3

The magnetization relaxation rate of small gamma-Fe2O3 particles dispersed in a silica matrix has been measured from 60 mK to 5 K. It shows a minimum around 150 mK, that can be dis…
