Rare-earth iron garnets (REIG) have recently become the materials platform of choice for spintronic studies on ferrimagnetic insulators. However, thus far studied mainly been REIG with a single rare earth species such as thulium, yttrium, or terbium garnets. In this study, magnetometry, ferromagnetic resonance, and magneto-optical Kerr effect imaging is used to explore continuous variation magn...

For applications making use of magnonic spin currents damping effects, which decrease the conductivity, have to be minimized. We here investigate magnon transport in an yttrium iron garnet thin film with strongly reduced effective magnetization. show that a three-terminal device conductivity can increased by factor up six current applied modulator electrode, generates compensation above thresho...

We report on the design, fabrication, and characterization of compact tunable yttrium iron garnet (YIG)-based RF resonators based ?m-sized spin-wave cavities. Inductive antennas with both ladder meander configurations were used as transducers between spin waves signals. The excitation ferromagnetic resonance standing in YIG cavities led to sharp resonances quality factors up 350. observed spect...
