Multiple spintronic functionalities into single zinc-ferrous ferrite thin films

چکیده
The ability to combine multiple spintronic properties in the ZnxFe3-xO4 system with different variants of its chemical composition offers a new and tantalizing route towards homodevices. This is mainly due advantage varying Zn component ZnxFe3-xO4, which leads possibility preserving spinel symmetry (within 5% lattice mismatch) while changing material from ferrimagnetic half-metal (x = 0) an insulating paramagnet 1). Here we demonstrate that thin films, grown ZnFe2O4 single phase target, laser-ablated under reduced atmosphere, exhibits reduction content, large 4πMS (6.5 kG), very low resistivity (25 mΩ cm) Verwey transition, all can be engineered by appropriate choice growth temperature. All these spectacular are confirmed ab initio calculations attributed inverse structure [Znx+2Fe1−x+3]A[Fe1+y+3Fe1−y+2]BO4-δ, where Fe+2 ions along Fe+3 occupy octahedral sites Zn+2 inverted sit tetrahedral sites. Phase formation laser ablated films compared bulk thermal equilibrium, shows there competition between O vacancies at various temperature zones.

متن کاملGrowth and crystallographic feature-dependent characterization of spinel zinc ferrite thin films by RF sputtering
ZnFe2O4 (ZFO) thin films exhibiting varying crystallographic features ((222)-epitaxially, (400)-epitaxially, and randomly oriented films) were grown on various substrates by radio-frequency magnetron sputtering. The type of substrate used profoundly affected the surface topography of the resulting ZFO films. The surface of the ZFO (222) epilayer was dense and exhibited small rectangular surface...

Thin Ni0.5 Zn0.5 Fe2 O4 ferrite films were grown on different condition on different substrates using pulsed laser deposition technique. Studying the influence of the energy of the laser beam, of the O2 pressure, of the substrate temperature, and of the distance between the target and the substrate on the microstructure and on the magnetic properties were established optimal conditions for PLD ...
