Abstract
The magnetic phase diagram has been calculated for two-sublattice ferrite type magnets AB 2 O 4 , with A and B sublattices partially filled by nonmagnetic ions. The fraction of magnetic ions was controlled separately for each sublattice and it has been denoted as X A and X B respectively. The system has been represented as a set of classical spins interacting with their nearest neighbours by Heisenberg hamiltonian. The numerical procedure used to calculate the magnetic ground state for each (X A, XB) pair was global energy minimisation by corrections of local spin directions. The resulting magnetic state has been analyzed by calculating the spin-spin correlation functions, Fourier transforms of magnetic order and some local variables like site and bond energy distributions. The final results is the magnetic phase diagram in the (X A, X B ) plane i..e. the determination of the types of magnetic order, the magnetic phase borders and the collinearity region for the dominant ferrimagnetic phase.
