Description

We have analytically calculated and compared the total magnetic energies of remanent magnetization states of hollow particles to find conditions for single-domain behavior. The size of the particles and the thickness of the spheroidal shell have been systematically varied for different hard and soft magnetic materials and the corresponding phase diagrams of the lowest-energy configurations are derived
