Part I - Experimental Studies of Spin Waves in a Micrometer-Thick Yttrium Iron Garnet filmAn investigation of spin wave dispersion in a micrometer-thick ferrimagnetic yttrium iron garnet (YIG) film has been conducted in various regimes. In the linear excitation regime, the dispersion of spin waves was characterized in an yttrium...
Liquid helium-3 is a remarkable substance. Even prior to the discovery of superfluidity in 1972, liquid helium-3 was the paradigm of a strongly interacting Fermi liquid. At even lower temperatures, liquid helium-3 undergoes a phase transition to a p-wave Fermi superfluid. Over 40 years since its discovery, superfluid helium-3 is...
