Typical soft magnetic properties induced by La doped CoTi-SrM hexaferrites and advances in texture research

Conventional permanent hexagonal ferrites may prohibit the soft magnetic properties through the effort of doping behavior. A typical case of this magnetic conversion is Co-Ti doped M-type strontium hexaferrites. On the basis of this system, we developed a novel foundation of La doped CoTi-strontium hexaferrites in present work and a promising result were obtained. Polycrystalline Sr1-xLaxFe10CoTiO19 (x= 0.00-0.10) hexaferrites present the admirable characteristics as general soft ferrites (high permeability mu low core loss P-cv), and retain the properties of permanent ferrites simultaneously. This extraordinary performance exhibit more appropriate candidate for multilayer inductors contrast to normal soft magnetic materials. Meanwhile, we presented a series of measurement results to investigate the morphology and texture of the sample, which revealed the internal structural feature systematically. (C) 2019 Elsevier B.V.
