Magnetocaloric materials: the search for new systems    [PDF]

Karl G. Sandeman

The prospect of efficient solid state refrigeration at room temperature is
driving research into magnetic cooling engine design and magnetic phase
transition-based refrigerants. We construct what we believe is the first
Ashby-style map of magnetic refrigerant properties, comparing popular materials
with limits derived from an idealised first order transition model. This
comparison demonstrates the potential for new magnetocaloric material systems
to be established through structural control and optimisation at the atomic-,
nano- and micro-scale.
