Polycrystalline NiZn ferrite doped with a small amount of Y3+ ions and having the composition of Ni0.42Zn0.58YxFe2-xO4, where x=0.00, 0.01, 0.02, 0.04, 0.06, 0.08 and 0.10, was analyzed. Specimens were prepared by the ceramic method. Thermo-magnetic analysis and evaluation of hysteresis loops parameters were chosen as main examination methods in this study. Various parameters, such as Curie temperature TC, coercive field Hc, remanent magnetic flux density Br, hysteresis loop area and amplitude/initial permeability were studied at low frequencies.
