Study of pulsed laser deposited magnetite thin film

Magnetic properties of magnetite thin films close to the Verwey transition

“…In this paper, we report a detailed study of the magnetic properties of magnetite film, prepared by PLD at heated substrate of 500 1C, which shows a clearer Verwey transition in comparison to the room temperature deposited film reported earlier by us [11]. Hence this film was chosen by us for carrying out detailed studies of M-H loops and magnetization, especially close to the Verwey transition temperature.…”

“…This is particularly remarkable for the magnetization, where sometimes one does not even notice a clear change close to T v [7,8]. We have recently reported some preliminary studies on the deposition of magnetite thin films [10,11]. These films were grown on fused quartz substrate by rf sputtering [10] and pulsed laser ablation (PLD) [11], with the substrate kept at room temperature.…”

These films were grown on fused quartz substrate by rf sputtering [10] and pulsed laser ablation (PLD) [11], with the substrate kept at room temperature. We had shown in these papers that while the film deposited by rf sputtering does not show a very clear Verwey transition in the resistivity, the same is clearly seen in the pulsed laser deposited film, both in the resistivity and the magnetization.…”

In-plane magnetization with high coercivity in terbium iron garnet thin films deposited on Pt/Si substrate by PLD

“…Depending upon deposition conditions textured growth has been reported in ferrite thin films [14,15]. As an example, epitaxial growth of Y 3 Fe 4 GaO 12 (YFGO) thin films on GGG substrate has been reported with just one XRD peak corresponding to (1 1 1) of garnet phase [16].…”

Influence of the Substrate and Precursor on the Magnetic and Magneto-transport Properties in Magnetite Films

“…For example, Bohra et al [19] have observed significant improves in the crystallinity and in the magnetic properties of annealed polycrystalline films, while Mantovan et al [18] correlate the number of vacancies and the stoichiometric characteristics with the magnetic and transport properties of the system.…”
