Magnetic and electronic studies of Cu80Fe5Ni15 granular ribbons
چکیده انگلیسی
Magnetic and electronic properties of granular Cu80Fe5Ni15 ribbons are investigated by magnetization measurements and first principle calculations. Magnetization variation versus temperature is found to obey the Bloch law, allowing us to calculate the spin wave stiffness constant D and the exchange constant A from the experimental results. The magnetic experimental results have been interpreted within the framework of random magnetic anisotropy (RMA) model. The results have shown the possibility to extend the application of RMA to the granular ribbons. Some fundamental parameters have been extracted from the approach to saturation magnetization. In addition, self-consistent ab initio calculations, based on Korringa-Kohn-Rostocker (KKR), are performed to investigate both electronic and magnetic properties. These calculations include spin polarized potential within the framework of the Coherent Potential Approximation (CPA).
