“…In 445–465 nm thick NFO films on ZGO, CGO and MAO, in-plane FMR measurements yielded easy plane type H a values of 0.1 kOe, 0.5 kOe and 2.6 kOe, respectively. We recently carried out studies on 2–30 m thick LPE grown Ni 0.85 Zn 0.15 Fe 2 O 4 ( NZFO) films on (111) and (100) MGO substrates 31 . An induced in-plane anisotropy field in the films was evident from the magnetization and FMR measurements.…”

“…It is however possible to achieve a significant modification of magnetic parameters in thin films. A variety of techniques were used in the past to synthesize films of NFO, including electrodeposition 22 , chemical vapor deposition 23 , microwave-assisted solvothermal process 24 , pulsed laser deposition (PLD) 25 – 29 , and liquid phase epitaxy (LPE) 30 , 31 . The objective in most of the past studies was to take advantage of strain due to film-substrate lattice mismatch to achieve a large growth induced anisotropy field.…”

“…Techniques such as PLD or chemical vapor deposition techniques are therefore not appropriate for deposition of films with thickness suitable for microwave device applications. Liquid phase epitaxy (LPE) with growth rates as high as 1 m/(min) is ideally suitable for the deposition of thick ferrimagnetic spinel and garnet films 31 – 34 . We report here on the synthesis by LPE and structural and magnetic characterization of films 2.5–16 m NFO films on MGO substrates.…”

This work focuses on the nature of magnetic anisotropy in 2.5–16 micron thick films of nickel ferrite (NFO) grown by liquid phase epitaxy (LPE). The technique, ideal for rapid growth of epitaxial oxide films, was utilized for films on (100) and (110) substrates of magnesium gallate (MGO). The motivation was to investigate the dependence of the growth induced anisotropy field on film thickness since submicron films of NFO were reported to show a very high anisotropy. The films grown at 850–875 C and subsequently annealed at 1000 C were found to be epitaxial, with the out-of-plane lattice constant showing unanticipated decrease with increasing film thickness and the estimated in-plane lattice constant increasing with the film thickness. The uniaxial anisotropy field Hσ, estimated from X-ray diffraction data, ranged from 2.8–7.7 kOe with the films on (100) MGO having a higher Hσ value than for the films on (110) MGO. Ferromagnetic resonance (FMR) measurements for in-plane and out-of-plane static magnetic field were utilized to determine both the magnetocrystalline the anisotropy field H4 and the uniaxial anisotropy field Ha. Values of H4 range from −0.24 to −0.86 kOe. The uniaxial anisotropy field Ha was an order of magnitude smaller than Hσ and it decreased with increasing film thickness for NFO films on (100) MGO, but Ha increased with film thickness for films on (110) MGO substrates. These observations indicate that the origin of the induced anisotropy could be attributed to several factors including (i) strain due to mismatch in the film-substrate lattice constants, (ii) possible variations in the bond lengths and bond angles in NFO during the growth process, and (iii) the strain arising from mismatch in the thermal expansion coefficients of the film and the substrate due to the high growth and annealing temperatures involved in the LPE technique. The LPE films of NFO on MGO substrates studied in this work are of interest for use in high frequency devices.

“…В основе данного явления лежит взаимодействие электрической и магнитной упорядоченных подсистем через механическую связь: возникающие в образце механические деформации посредством внешнего воздействия на одну из подсистем (электрическую либо магнитную) приводят к соответствующему отклику в другой подсистеме. Воздействие магнитной подсистемы на электрическую условились называть прямым МЭ-эффектом [4], если же изменяется магнитное состояние во внешнем электрическом поле -то это обратный эффект [5]. Наиболее отчетливо МЭ-эффект наблюдается в слоистых композиционных структурах, в которых обе упорядоченные подсистемы пространственно отделены друг от друга.…”

In the layered ferromagnetic /ferroelectric structures in the form of cobalt, nickel or permendur layer on a ferroelectric substrate of lead zirconate titanate obtained by ion-beam sputtering – deposi-tion, relative strains due to mismatch of crystal lattices of mating materials at the metal / substrate in-terface make a more noticeable contribution to the magnetoelectric response than those associated both with the magnetostriction of the ferromagnetic layer and with the piezoelectric effect of the fer-roelectric substrate. The structures obtained are characterized by the thermal stability and reproduci-bility of magnetoelectric characteristics and can be used as converters of magnetic and electrical quantities, for example, in magnetic field sensors and actuators.
