ABSTRACT
Sn doped CuInO2 thin films having a single delafossite phase have been synthesized by magnetron sputtering technique. A gradual decrease in the activation energy from 0.43 to about 0.10 eV and a large increase in conductivity are observed in Sn doped samples with increasing fraction of crystallites having (006) orientation due to an increase in substrate temperature. Due to thermally activated carrier transport along O-A-O layers and activated carrier generation along BO6 layers, crystallite orientation becomes a crucial factor in controlling the conduction in delafossite thin films.

    We present a new type of temperature driven spin reorientation transition (SRT) in thin films. It can occur when the lattice and the shape anisotropy favor different easy directions of the magnetization. Due to different temperature dependencies of the two contributions the effective anisotropy...
