摘要：
Fe-doped In2O3 thin films were deposited on MgO substrates by pulsed laser deposition (PLD). The linear decrease in lattice constant with increasing Fe concentration of up to 18% suggests the incorporation of Fe atoms into In2O3 lattice matrix. The PLD grown films exhibited ferromagnetism at room temperature with a strong magnetic anisotropy. The observed anomalous Hall effect (AHE) indicates that spin polarized charge carriers play an important role in the origin of ferromagnetism in these oxides. Our observations, including AHE, magnetic anisotropy, and structural analysis provide strong evidence of intrinsic ferromagnetism at room temperature in these materials. [doi:10.1063/1.3678038]
