The system absorbs and releases heat in cycles, acting as both a refrigerator and a heat pump.

Fe-based amorphous alloys offer a promising alternative with low coercivity and minimal core losses, but their low saturation magnetization hinders their use in high-power-density devices.

RECENTLY 1 it has been suggested that interstitial hydrogen in a face-centred cubic lattice will produce embrittlement and cause delayed failure under the appropriate conditions. Basically ...
