    Nov 15, 2020 Fe-Si/MnO 2 SMCs were prepared successfully via ball milling.. The effect of MnO 2 content on microstructure and magnetic properties was investigated.. The MnO 2 insulating layer is uniform and its thickness increases with the increased MnO 2 content.. When the MnO 2 content increases from 0.0 wt% to 10.0 wt%, H c increases gradually, M s and P t exhibit opposite trend
