We present the structural and magnetic properties of Pr0.6Sr0.4Mn1 − xFexO3 (x = 0, 0.1, 0.2, and 0.3) com- pounds. Samples have been prepared by the ball milling method. Rietveld refinements of the X-ray powder diffrac- tion data show that all our

The magnetic properties of M-type Strontium hexaferrites can be modified by partially substituting Fe ions by other metallic ions. In this work, we report on the effect of the substitution of Ti 2+ and Ru 4+ ions for Fe 3+ ions on the magnetic proper

In the present work, we analyze the magnetic transition and magnetic entropy change $ \vert\Delta S_{M}\vert$ of Pr0.6Sr0.4Mn1-x Fe x O3 samples. Using Arrott plots, we report that the phase transition for Pr0.6Sr0.4MnO3 sample is of second order, wh
