Magnetotransport in Sr2CrWO6 thin films — •Petra Majewski, Stephan Geprägs, Andrea Boger, Matthias Opel, and Rudolf Gross — Walther-Meissner-Institut, Bavarian Academy of Sciences, Walther-Meissner-Str. 8, 85748 Garching, Germany

We report on the fabrication and characterization of thin film samples of Sr2CrWO6 by PLD (Pulsed Laser Deposition). The growth process was monitored by RHEED (reflection high energy electron diffraction) and the high crystalline quality of the thin films was checked by X-ray diffraction. The Curie temperature TC was found to exceed 400K from SQUID magnetization measurements. The magnetotransport properties of the samples were investigated in the temperature range from 5K to 300K and magnetic fields up to 14T. Hereby the magnetic field was applied in several directions with respect to the thin films. Preliminary results indicate that the transport properties are close to a metal-insulator transition. We also discuss an interesting fine structure in the MR at low fields, which is highly sensitive on the direction of the applied magnetic field.
