Remanence properties of Co-precipitated cobalt ferrite
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...

| Sumario: | 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. 2001 Elsevier Science B.V. All rights reserved. |
