چکیده انگلیسی
Magnetic soft-hard composites of perovskite La-Sr manganite (LSMO) and M-type Sr-hexaferrite (SrM), LSMO(1 â x)-SrM(x) with xâ¯=â¯0, 0.05, 0.1, 0.3, 0.5, and 1.0 were prepared by solid-state reaction. Although the two phases coexist without forming secondary phases, the saturation magnetization (MS) value of the LSMO phase decreased with the doping of SrM (xâ¯â¥â¯0.05). Clear double hysteresis behaviors were observed in the samples with xâ¯=â¯0.3 and 0.5, while single soft magnetic hysteresis was noted in the samples with xâ¯â¤â¯0.1. In the M-T measurement, the composite with xâ¯=â¯0.5 exhibited a diffusive temperature dependence of magnetization unlike that of non-doped LSMO (xâ¯=â¯0). Weakening of ferromagnetism in the composites can be attributed to interatomic diffusion between the two phases occurring during calcination at 1200â¯Â°C.
