Optimization of Materials for Magnetic Refrigeration and Thermomagnetic Power Generation
<p>The magnetocaloric effect, by which a magnetic material experiences a change in temperature due to an applied magnetic field, can be used for refrigeration. The corollary to the magnetocaloric effect -- known as the pyromagnetic effect -- is the phenomenon by which a magnetic material …

Low-dimensional and frustrated magnetism in complex lanthanide oxides
This thesis reports the structural and magnetic behaviour of complex lanthanide oxides exhibiting low-dimensional and/or geometrically frustrated magnetism. Materials displaying these phenomena are well studied as hosts for novel magnetic states such as spin liquids, and for applications such as …
