Properties of magnetite
WebApr 11, 2024 · Since the magnetic properties and transition temperature are highly sensitive to the chemical composition, it is essential to understand and monitoring these properties … WebIn this thesis, I focus on the magnetic properties of three transition metal oxides. The first study I present in this thesis is on the botallackite cuprate Cu2 (OH)3Br. I present the results for the excitation spectrum of the material, obtained through a combination of first-principles methods, linear spin wave theory and exact diagonalization.
