In order to investigate the magnetic anisotropy, low field magnetization measurements have been carried out on various samples of magnetically annealed Metglas 2605 CO. The as-fabricated material exhibits a magnetic anisotropy with the easy axis along the ribbon length. By using the magnetic annealing treatment which yields an enhanced value for the magnetomechanical coupling factor, a magnetic anisotropy is induced with the easy axis in the plane of the ribbon and perpendicular to the length. A value of K=4.3×103 erg/cm3 is calculated for the induced anisotropy energy constant at room temperature. Using a model based on simple domain rotation, a value of λs=25×10−6 is estimated for the corresponding saturation magnetostriction. The anisotropy increases 37% when the temperature is reduced to 77 °K. Values are presented for the saturation magnetization, domain magnetization, coercive field, and initial permeability.
