“…From this an in-plane lattice parameter of a = (8.08 ± 0.01) Å identical to the lattice parameter of the cubic MgAl 2 O 4 substrate is obtained. This results in a tetragonal distortion of c/a = 1.052 ± 0.003, which is significantly higher than reported for epitaxial NiZAF films before [3][4][5].…”

“…The material is insulating and ferromagnetic at room temperature with low magnetic damping. Therefore, it can be considered as a good candidate [3][4][5] among few other materials, e.g., MAFO [6,7], all-perovskite oxides [8], and Fe alloyed with V and Al [9] as replacement, for the well-known magnetic insulator yttrium iron garnet (YIG) [10,11]. YIG exhibits comparable magnetic properties as NiZAF, however, it has the complex garnet structure and thin-film growth requires gadolinium gallium garnet (GGG) as substrates thus limiting a wide applicability.…”

Control of site occupancy by variation of the Zn and Al content in NiZnAl ferrite epitaxial films with low magnetic damping

et al. 2022

The structural and magnetic properties of Zn/Al doped nickel ferrite thin films can be adjusted by changing the Zn and Al content. The films are epitaxially grown by reactive magnetron sputtering using a triple cluster system to sputter simultaneously from three different targets. Upon the variation of the Zn content, the films remain fully strained with similar structural properties, while the magnetic properties are strongly affected. The saturation magnetization and coercivity as well as resonance position and linewidth from ferromagnetic resonance (FMR) measurements are altered depending on the Zn content in the material. The reason for these changes can be elucidated by investigation of the x-ray magnetic circular dichroism spectra to gain site-and valence-specific information with elemental specificity. Additionally, from a detailed investigation by broadband FMR, a minimum in g factor and linewidth could be found as a function of film thickness. Furthermore, the results from a variation of the Al content using the same set of measurement techniques is given. Other than for Zn, the variation of Al affects the strain and even more pronounced changes to the magnetic properties are apparent.

“…In comparison to the two previous publications on NiZAF, the ratios of Zn to the other metals of the entire Zn series are between the Zn-deficient NiZAF grown by PLD [3] and the Zn-rich NiZAF grown by RMS [4]. The structural analysis of the entire Zn series results in NiZAF films, which are even more strained compared to previous publications [3][4][5].…”
