  4. Abstract:
  5. The variation of the applied field results in a subsequent change of magnetization with time. There is a relationship between the coercivity (Hc), as the equilibrium characteristic of the system, and its magnetic stability (1/S), as a parameter characterizing the time dependence. 1/S as a function of Hc has been measured and studied for different Fe1-xCox samples. We synthesized several samples with different values of x by applying various magnetic fields during the grains' growth, and observed a linear relationship between 1/S and Hc. © 2007 Elsevier B.V.
