The typical magnetic phase diagrams of a random site Heisenberg magnet with competitive exchange interactions of the nearest neighbours are investigated. It is emphasized that there appear magnetic states which are superpositions of the long‐range magnetic ordering of some spin vector components and the spin‐glass freezing‐in of other components, namely, the asperomagnetic (random noncollinear ferromagnetic) state, the antiasperomagnetic (random noncollinear antiferromagnetic) one, and the noncoplanar canted one.
