Nature Materials 9, 956 (2010). Phys. Ferrimagnetism, type of permanent magnetism that occurs in solids in which the magnetic fields associated with individual atoms spontaneously align themselves, some parallel, or in the same direction (as in ferromagnetism), and others generally antiparallel, or paired off in opposite directions (as in antiferromagnetism). Ferromagnetism is the only magnetization with all same direction moments. These strong interactions cause the alignment of magnetic domains in the same direction. ferromagnetism meaning: 1. the type of magnetism (= the force that makes certain objects move towards it) that iron has 2…. The ferromagnetism appears in degenerate or nondegenerate semiconductors, and even in insulators, at concentrations of 3d dopants that lie far below the percolation threshold x p associated with nearest-neighbor cation coupling.
