 Nguyen Anh Tuan* and Nguyen Phuc Duong, “Structural, magnetic, and magnetotransport properties of NiMnSb thin films deposited by flash evaporation”, Applied Physics Letters  99 (2011) 162507-3.

Abstract: To date, the use of flash evaporation (FE) as a deposition technique for NiMnSb thin films has not yet been reported. In this letter, we report on NiMnSb thin films deposited on heated Si (111) substrates at 300 C via FE. Investigations of the structural characteristics and magnetic and magnetotransport properties of these thin films show typical features of a half-metallic ferromagnetic semi-Heusler alloy. The origin of the film’s extraordinary magnetotransport behavior is examined under the perspective of spin-order levels attached to a grain-grain boundary-type structure.
