High magnetic field studies of the shape memory alloy AuZn

Conference item

This article reviews high magnetic field magnetization measurements of the shape memory alloy AuZn. These measurements elucidate the underlying electronic mechanism driving this effect. The application of high magnetic fields (up to 65 T), in combination with exceptional sample purity and light electronic effective masses enables the observation of magnetic quantum oscillations over an unprecedented range of temperatures (up to 100 K); thus the electronic band structure can be tracked across the shape memory phase transition (at T=67 K) and the Fermi surface nesting event driving it identified. © 2006 Elsevier Ltd.
