Resumen
Isothermal remanent magnetization (IRM) and DC demagnetization (DCD) curves of a co-precipitated cobalt ferrite
sample were obtained. From the IRM and DCD data, the Henkel plot was obtained and analyzed in the Preisach model
framework. The Henkel plot data are below the Wohlfarth line that indicates a dominant local disorder (demagnetizinglike
e!ect). Forward and reverse switching "eld distribution curves were obtained from di!erentiation of the IRM and
DCD curves. The peak values of these switching "eld distributions di!er by a factor of about 2.7.
