Abstract
The changes of ZnFe2O4 caused by mechanical activation as well as the struc tural evolution of non-activated and mechanically activated zinc ferrite oc curring during heating, have been investigated by in situ Mossbauer spectro scopy. Attention is directed to mechanically induced changes in magnetic pr operties of zinc ferrite, the variation of nuclear quadrupolar interactions , the thermally induced changes of the Mossbauer shift, and also to the str uctural response of mechanically activated zinc ferrite to changes in tempe rature.
