Abstract |
We have studied the magnetization in Co86Tb14/Pt multilayers under fields up to 1.8 T and as at room temperature. As the do-Tb layer thickness (tCoTb) decreases below 200 Å the saturation magnetization magnetization (M) increases, the rectangularity of the M-H loops and the coercivity (Hc ) decrease. The effective anisotropy Keff of the multilayers was determined by a torque magnetometer. The product Keff×tCoTb shows a linear dependence with tCoTb as normally found for the superlatices yielding the bulk and surface anisotropies of 106 erg/cm3 and –0.2 erg/cm2 , respectively. These results are explained in terms of an interfacial Co-Pt layer. Keff and Hc are related by the equation Hc = α Keffn/M with the fitting parameters α and n. |
