Epitaxial NbFe2 thin films prepared by PLD — •Andreas Reisner, Silvia Haindl, Bernhard Holzapfel, and Ludwig Schultz — IFW Dresden, Institute of Metallic Materials, 01069 Dresden, Germany
The hexagonal Laves phase NbFe2 shows an interesting itinerant magnetic behaviour whose ferromagnetic transition at low temperatures is strongly dependent on the stochiometry.
We report on successful preparation of epitaxial thin films grown on single crystalline Al2O3 (001) substrates by an UHV pulsed laser deposition process. Structural investigation show a twofold epitaxial relation of Al2O3(001)[100]||NbFe2(001)[100] and Al2O3(001)[100]||NbFe2(001)[210]. Magnetic and transport properties of films with various compositions near the stochiometric point have been investigated.
