Magnetic and dielectric properties of Nd–Mn substituted Co2Y-hexaferrites

Designing the new multifunctional ferromagnetic materials for multilayer chip inductor has attracted widespread interest in recent years. Co2Y strontium hexaferrites with composition of Sr2−xNdxCo2Fe12−yMnyO22 (for X = 0.00–0.1, Y = 0.00–1.0) were fabricated by the simple economical sol-gel autocombustion method. The surface morphology of the synthesized materials was investigated by using scanning electron microscopy and the particles were in...
