Abstract :
Summary form only given. Substitution of La and/or La-Co into Sr hexaferrite (SrM) has been reported to improve magnetic properties. Meanwhile, we have observed that the substitution of Sm for Sr in SrM produces an improvement in the coercivity similar to that noted for SrM with La additives. In an effort to improve the magnetic properties of SrM with other rare-earth element additives, Nd doped SrM samples with various Nd/sup 3+//Sr/sup 2+/ ratios were prepared by hydrothermal synthesis and subsequently calcined at 1000/spl deg/C to 1250/spl deg/C.
