摘要：

Magnetite thin film with a predominant (1 1 0) texture has been deposited by pulsed laser ablation of alpha-Fe2O3 target onto fused quartz substrate. Spontaneous magnetization of 5400 G and room temperature electrical resistivity of 4.2 x 10(-3) Omega cm were measured for an annealed magnetite thin film. Zero-field-cooled magnetization data clearly show the Verwey transition near 120 K through an abrupt change, and is consistent with the resistivity measurement. (c) 2006 Elsevier B.V.
