Abstract
The peak value of switching field distribution χmax, coercivity Hc, and saturation magnetization Ms are measured as functions of temperature T in Co-γ-Fe2O3 and γ-Fe2O3 powders. It is found that χmax has a maximum at T=Tp and evidence is presented also for the existence of a theoretically predicted minimum at T=T m
