Magnetic excitations in the frustrated system Yb3Ga5O12
The use of magnetic frustrated compounds has been proposed for low temperature refrigeration applications. Indeed, the presence of soft modes in such systems enhances magnetocaloric effects as compared to usual paramagnets. The garnet Yb3Ga5O12 (YbGG) is a potential candidate for these applications. It is proposed to investigate the low energy spin dynamics of YbGG using single crystal neutron spectroscopy and to follow its evolution as a function of temperature (0.2-10 K) and magnetic field (0-2 T).
