Matteucci effect

Matteucci effect is one of the magnetomechanical effects, which is thermodynamically inverse to Wiedemann effect.[1] It is observable in amorphous wires with helical domain structure, which can be obtained by twisting the wire, or annealing under twist. The effect is most distinct in the so-called 'dwarven alloys' (called so because of the historical cobalt element etymology), with cobalt as main substituent.[2][3]
