In this paper, we report the transport properties of Cr-doped Ti2O3 thin films. The thin films were grown on α-Al2O3 s012d substrates by pulsed-laser deposition. X-ray diffraction and transmission electron microscopy results show that the films are single corundum phase. All of (CrxTi1−x)2O3 show semiconducting behavior. Without doping, pure Ti2O3 thin films show positive magnetoresistance (MR) of 23% at 2 K. The MR behavior changed dramatically after doping with Cr. Sample (Cr0.1Ti0.9)2O3 shows MR=−360% at 2 K. All of the Cr-doped films are ferromagnetic up to room temperature.
