Abstract
The La-Zn substituted Sr-Magnetoplumbite ferrite LaxSr1-xZnxFe12-xO19 (x =
0 0.6) fine particles were prepared to investigate the effects of the subst
itution on the magnetic properties of the samples. It is observed, with inc
reasing substitution rate, that the saturation magnetization M-s as well as
the magnetocrystalline anisotropy constant K-U1 increased up to a maximum
for about x = 0.3, then decreased rapidly. The value of dH(c)/dT also reduc
ed rapidly from about 5.5 Oe K-1 (for x = 0) to - 0.5 Oe K-1 (for x = 0.4).
A qualitative explanation was given with respect to the hypothesis of crys
talline electronic field and the single ion model. (C) 2000 Elsevier Scienc
