Procesos reversibles durante la inversión de la magnetización en la ferrita de cobalto

Abstract

A study of the magnetization reversal process at 300 K in a co-precipitated cobalt ferrite material was carried out. The evolution of the reversible M rev and irreversible Mirr magnetization components were determined by measuring sets of recoil curves from different points on the initial magnetization curve and mayor demagnetization curve (Isothermal Remanent Magnetization and Direct Current Demagnetization Methods). The M rev(Mirr)Hi curves at constant Hi
