Study of pulsed laser deposited magnetite thin film
Abstract
Magnetite thin film with a predominant (1 1 0) texture has been deposited by pulsed laser ablation of α-Fe 2O 3 target onto fused quartz substrate. Spontaneous magnetization of 5400 G and room temperature electrical resistivity of 4.2×10 -3 Ω 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.
