Electrodynamic study of YIG filters and resonators

Numerical solutions of coupled Maxwell and Landau-Lifshitz-Gilbert equations for a magnetized yttrium iron garnet (YIG) sphere acting as a one-stage filter are presented. The filter is analysed using finite-difference time-domain technique. Contrary to the state of the art, the study shows that the maximum electromagnetic power transmission through the YIG filter occurs at the frequency of the ...

YIG Film for Magnetic Field Sensor

Single crystal Y3Fe5O12 (YIG) lm was grown onto (111) oriented gadolinium gallium garnet (GGG) substrate by the liquid phase epitaxy (PLD) technique. The X-ray di raction measurements showed that epitaxial growth of the lm along its (111) axis. The surface characteristic was investigated by atomic force microscopy (AFM) measurement. The magnetic eld sensor consisted of a rectangular shape with ...

Intrinsic spin Seebeck effect in Au/YIG.

The acute magnetic proximity effects in Pt/YIG compromise the suitability of Pt as a spin current detector. We show that Au/YIG, with no anomalous Hall effect and a negligible magnetoresistance, allows the measurements of the intrinsic spin Seebeck effect with a magnitude much smaller than that in Pt/YIG. The experiment results are consistent with the spin polarized density functional calculati...

Robust longitudinal spin-Seebeck effect in Bi-YIG thin films

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 electricit...
