“…l r is sensitive to microstructure, and by extension, the defect structure. It has been shown that dislocation networks create periodic, localized stresses, which hinder the motion of the domain walls [36], causing an increase in coercive force and a decrease in relative permeability.…”

“…However, the coercivity of the film was significantly higher than the reported bulk values. Large values of coercivity are believed to arise because of strain fields that are expected to be present in the ultra-thin crystalline films 20 . The other factor, which could equally be responsible for the observed large coercivity, is the film's high surface roughness and the corresponding stray fields.…”

In recent years, the coupling of magnetic insulators (bismuth-doped yttrium iron garnet, Bi-YIG) with platinum has garnered significant interest in spintronics research due to applicability as spin-current-driven thermoelectric coatings. These coatings bridge the gap between spintronics technologies and thermoelectric materials, providing a novel means of transforming waste heat into electricity. However, there remain questions regarding the origins of the spin-Seebeck effect (SSE) as well as claims that observed effects are a manifestation of magnetic proximity effects, which would induce magnetic behavior in platinum. Herewith we provide support that the voltages observed in the Bi-YIG/Pt films are purely SSE voltages. We reaffirm claims that magnon transport theory provides an ample basis for explaining SSE behavior. Finally, we illustrate the advantages of pulsed-laser deposition, as these Bi-YIG films possess large SSE voltages (even in absence of an external magnetic field), as much as twice those of films fabricated via solution-based methods.

High coercive garnet-ferrite films are being synthesized for thermo-magnetic recording, for example, by focused laser beams. These films can be characterized by a couple of parameters very suitable for recording reconfigurable magnetic atomic traps whose geometry is visible. On the other hand, slightly other films can be used for contact printing of high density and weak residual magnetization records in criminalistics. Both types are investigated experimentally in this work.
