Polycrystalline NiFe2O4 (NFO) thin films are grown on (111) platinized Si substrates via chemical solution processing. θ-2θ x-ray diffraction, pole figures and electron diffraction indicate that the NFO has a high degree of 〈111〉 uniaxial texture normal to film plane. The texturing is initiated by nucleation planes at Pt interface enhanced with decreasing thickness. As magnetic easy-axis 〈111〉, out-of-plane magnetization exhibits improved Mr/Ms coercivity respect randomly oriented silicon...
Chemical solution deposition is used to grow biaxially textured NiFe2O4 (NFO) thin films on (0001) sapphire substrates; a high degree of out-of-plane orientation in the 〈111〉 direction confirmed by θ–2θ X-ray diffraction and pole figures. φ-scanning indicates in-plane texture an epitaxial relationship between NFO (111) Al2O3 two crystallographic variants. The magnetization exhibits improved Mr/Ms from 0.5 110 nm-thick 0.8 60 films. Compared uniaxially platinized silicon, coercivity reduced...
(111)‐oriented epitaxial thin films of nickel ferrite ( NFO ) are grown on c ‐plane sapphire [α‐ Al 2 O 3 (0001)] substrates using a chemical solution deposition technique. The processing conditions, including pyrolysis and annealing temperatures, varied to achieve film that shows maximum texture epitaxy. It is shown increasing the temperature 400°C decreasing 750°C for 10 min result in highest degree films. Lower thickness also leads higher texture. Microstructural studies confirm an...
