Pressure effects on electronic structure and magnetic properties of anisotropic metallic compounds

Pressure effects on electronic structure and magnetic properties of anisotropic metallic compounds

Pressure effects on electronic structure and magnetic properties of anisotropic metallic materials (CrB₂, FeGe₂, LaFeAsO) are investigated. Magnetic susceptibilities of CrB₂ and FeGe₂ compounds were studied under hydrostatic pressure at fixed temperatures, 77 and 300 K. In order to analyze the exper...
