講演テーマ:
 The role of interfaces and defects on halfmetallic heterostructures

Abstract:
Halfmetallic materials have attracted significant research attention research in the past decade due to their predicted 100% spin polarisation. The halfmetals incorporation in heterostructure devices is very demanding since it requires atomic control of the interfaces and structure of the layers. In this talk I will present a correlation between the functionality of model spintronic devices and their atomic structure, with special focus on the effect of intrinsic defects and interfaces on halfmetallicity and ultimately on device performance.
