Ultrafast giant magnetic cooling effect in ferromagnetic Co/Pt multilayers

The forced alignment of magnetic moments leads to a large change in entropy, which can be used to reduce the temperature of a material. Here, the authors show that this magnetic cooling effect occurs on a femtosecond time scale in cobalt–platinum nano-multilayers.
