Sperimagnetism
Sperimagnetism is the equivalent of ferrimagnetism for a disordered system with two or more species of magnetic moments, with at least one species locked in random magnetic moments. Sperimagnets possess a permanent net magnetic moment. When all species are the same, this phase is equivalent to asperomagnetism.
