Our data for the temperature dependence of the low field magnetization and the saturation coercive force of the samples evidenced the occurrence, in different temperature ranges, of Neel- and Brown-type relaxation processes whose characteristics were largely influenced by strong dipolar interparticle interactions.3 p.application/pdfeng(c) IEEE, 1998Propietats magnètiquesCompostos de ferroRelaxació magnèticaMagnetismeMagnetic propertiesIron compoundsMagnetic relaxationMagnetisminfo:eu-repo/semantics/article133711info:eu-repo/semantics/openAccess
