RESEARCH AND DEVELOPMENT TO INVESTIGATE THE MICROSTRUCTURE OF THE INTERNAL MAGNETIC FIELD IN FERRO-, FERRI-, AND ANTIFERROMAGNETIC SOLIDS

Abstract

A number of research projects dealing with funda mental interactions and the microstructure of internal fields in selected magnetic materials were initiated or continued. The magnetocrystal line anisotropy and electron spin resonance in single crystals of gadolinium metal were investi gated. The thermal expansion anomalies near the Curie points of the ferromagnetic metals, gadolinium and nickel were analyzed. An investi gation to look for coherency strains in the cobalt particles precipitated in a copper-cobalt alloy was initiated using the nuclear resonance fre quency of the particles as a sensitive probe. The same alloy system is under study by ferro magnetic resonance techniques with a view to understanding its magnetic annealing. The nuclear magnetic resonance of both Mn and As in the com pound MnAs has been observed. (Author)
