Abstract

Magnetic and magneto-optical properties of Mn_xCuBi ( x = 0.75 - 3.5) thin films are presented. With increasing Mn concentration x, the perpendicular anisotropy constant (K_u the remanence squareness (S = M_r/M_s) and the coercivity (H_c)the perpendicular hysteresis loop increase. Remanence squareness as high as 0.95 has been obtained. Kerr rotation (θ_k) and ellipticity (η_k) spectra from all samples measured from substrate side are similar, with θ_k exhibiting a broad peak in the blue wavelength region with maximum Kerr rotation up to 0.7 degrees.
