INVESTIGATION OF THE STRUCTURAL AND MAGNETIC PROPERTIES OF THIN FERROMAGNETIC FILMS
Abstract
The principle object of the research is the correlation of the magnetic and structural properties of thin ferromagnetic films. Described in detail are the instrumentation, the film preparation and the first results obtained with 77:23 permalloy films. The structural investigation was carried out by using electron microscopy and electron diffraction techniques. Replicas of the surface of the films indicated the presence of foof a roughness which, at present however, has not been correlated to the magnetic uniaxial anisotropy h is the correlation of the magnetic and structural properties of thin ferromagnetic films. Described in detail are the instrumentation, the film preparation and the first results obtained with 77:23 permalloy films. The structural investigation was carried out by using electron microscopy and electron diffraction techniques. Replicas of the surface of the films indicated the presence omeasurement of the angular dependence of the torque with a sensitive torque magnetometer. The magnetic data are discussed in terms of the behavior of single domain and multi domain magnetic particles. (Author)
