Low-temperature magnetic hysteresis properties of multidomain single-crystal titanomagnetite

摘要: The low-temperature magnetic hysteresis characteristics of multidomain titanomagnetite were fitted by a mixed coercivity model in which magnetocrystalline-controlled and magnetostriction-controlled domain-wall pinning play an important part. effective contribution the former was found to decrease systematically with increasing titanium content for compositions range Fe2.48Ti0.52O4Fe2.35Ti0.65O4. In agreement model, observed remanence transitions characteristic peaks on susceptibility vs. temperature curve became less pronounced as increased. problems using these features means identifying carriers natural remanent magnetization are discussed.
