STUDIES OF RARE-EARTH SUBSTITUTED NICKEL ZINC FERRITES

Martin Šoka - Mariana Ušáková - Elemír Ušák

   Raw compounds with the chemical composition Ni_0.42Zn_0.58La_xFe_2-xO₄ (x = 0, 0.01, 0.02, 0.04, 0.06) were prepared using standard ceramic technique. The magnetic properties and magneto-chemical composition and structure of various doped nickel zinc ferrites were estimated by means of thermo-magnetic analysis of susceptibility temperature behaviour and magnetic hysteresis loop meas-urement.

Keywords: rare-earth, substituted ferrites, radio to microwave ferequencies
