Abstract

Effect of exchange-bias coupling between ferromagnetic (FM) layer and antiferromagnetic (AFM) underlayer on the H-field and thermal reversal properties was studied analytically by minimizing the free energy E(α, β) of the bilayer system. Correlation between the effective-thermal-stability-factor (K_uV*/k_BT)_eff, coercivity H_c and parameters of the bilayer system is presented. Emphasis is on analyzing the energy-barrier E_B influence upon the moment reversal properties.
