Magnetic properties (ground state, magnetic phase diagram, phase transitions in a magnetic field) of two- and three-dimensional lattices of ferromagnetic granules with dipole intergranule interaction are studied. The basic attention is given to lattices of non-spherical granules (prolate and oblate ellipsoids of revolution) and their limiting shapes––rod-like and disk-like granules. The analysis shows that conclusions of the theory agree with results of a series of experiments.
