摘要
The thermal variation of M(r)/M(s) and H-c reveals that compositions of Ni0.6Zn0.4Fe2O4 + SnO2 contain SD + MD, i.e., mixed domain state behaviour. With substitution of Sn4+, M(r)/M(s), decreases while H-c increases. Both of these parameters decrease with increasing temperature, which is related to a decrease in the anisotropy constant K-1. The variation of n(B) (77 K) with the concentration of Sn4+ suggests that canted types of spins are favoured with substitution of Sn4+.
