“…For instance, alkali metal ions, alkali-earth metal ions, transition metal ions, and rare earth metal ions have been applied to dope FPMs individually or jointly [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34]. Specially, La-Ca-Co joint doping has been verified as an effective approach to remarkably enhance the overall magnetic properties of M-type Strontium ferrite (SrM ferrite) magnets [35][36][37][38][39][40].…”

The crystallographic alignment, microstructure and magnetic properties were studied for La 0.6 Ca 0.6 Sr 0.1 Fe 12.4 Co 0.4 O 19 ferrite permanent magnets prepared with standard ceramic method. The effect of cold isostatic pressing (CIP) and sintering temperature on the structural and magnetic properties of the magnets were investigated. The CIP significantly improves the density of the green compact and final magnets, but undermines the crystallographic alignment of the magnets simultaneously. As a result, the remanence of the magnet achieves optimal value under the compromise between the increased density and the degraded alignment. Moreover, the coercivity of the magnet increases linearly with the increment of the CIP pressure due the fact that CIP processed samples bear more uniform and finer grains in favor of high coercivity. Under optimal CIP pressure and sintering temperature, the magnet obtains best magnetic properties of B r of 0.439 T, H cj of 396 kA m −1 , H cb of 311 kA m −1 , and (BH) max of 35.8 kJ m −3 .
