摘要：

Pulsed laser deposition technique is used for fabrication of multilayer thin film of indium oxide (In(2)O(3)) and iron oxide (Fe(3)O(4)). X-ray diffraction study shows that In(2)O(3) film is highly oriented along (222) direction. The optical band gap of the multilayer is observed to be 3.65 eV. The film shows n-type behavior with resistivity, carrier concentration, and mobility of 5.59 x 10(-4) Omega.cm, 2.33 x 10(20) cm(-3), and 48 cm(2) v(-1) s(-1) Magnetic measurement shows that the film is ferromagnetic at room temperature. Hysteresis measurements at 5 K after field cooling show a shift and broadening of the hysteresis loop, which is due to exchange bias coupling. (C) 2010 Elsevier B.V. All rights reserved.
