Effect of Co-doping Calcium and Scandium on Strontium Hexaferrite: Structural, Magnetic and Mossbauer Study. [PDF]

, 2020
M-type hexaferrite such as barium hexaferrite (BaM) and strontium hexaferrite (SrM), have a wide range of applications because of its high saturation magnetization, coercivity and remanance values. The magnetic properties of such materials can be altered

Development of Strontium Hexaferrite Magnets from Celestite Ore and Blue Dust

, 2008
Ph.D.Among the class of permanent magnets, M-type ferrites are by far the most important permanent magnetic materials. The M-type ferrites or hexaferrites are characterized by compound having general formula MFe12O19 (M = Sr, Ba, Pb) with hexagonal ...
