摘要：
Series of CoxCr1-x thin films have been evaporated under vacuum onto Si (100) and glass substrates. An alternating gradient field magnetometer is used to characterize the static magnetic properties of the samples and Brillouin light scattering is used to study their dynamic magnetic properties. The in-plane easy magnetization axis is found for all samples. Using these results, we computed the first, second and uniaxial magnetic anisotropy factors by several methods. Values of the computed effective magnetic anisotropy factors higher than 10(6) erg cm(-3) have been found. The results are discussed and correlated. (c) 2012 Elsevier B.V. All rights reserved.
