New Nanomaterial for Future Magnetic Fridges
Roland Piquepaille writes "Magnetic refrigerators offer significant advantages when compared with current vapor-compression ones, such as gains in energy efficiency, lower cost of operation or elimination of environmentally damaging coolants. Unfortunately, all the materials which have been tested in the last fifty years suffer from hysteresis losses, lowering the energy available for cooling.
