High-entropy oxide thin films have recently been introduced as an attractive strategy to design and enhance ferroic properties. Here, the authors perform element-sensitive x-ray absorption spectroscopy magnetometry on high-entropy perovskite films, shedding light how different transition metal elements contribute overall magnetic response. The results demonstrate not only disorder can lead enhancement of properties but also provide a route towards further improvements other desired in...
Magnonics, which harnesses the unique properties of spin waves, offers promising advancements in data processing due to its broad frequency range, nonlinear dynamics, and scalability for on-chip integration. Effective information encoding magnonic systems requires precise spatial temporal control waves. Here, we demonstrate rapid optical spin-wave transport hybrid magnonic-plasmonic structures. By using thermoplasmonic heating yttrium iron garnet films integrated with gold nanodisk arrays,...
The impact of plasmonic surface lattice resonances on the magneto-optical properties and energy absorption efficiency has been studied in arrays [Co/Gd/Pt]N multilayer nanodisks. Varying light wavelength, disk diameter, period array, it is demonstrated that allow all-optical single pulse switching nanodisk with an 400% smaller than needed to switch a continuous film. Moreover, Faraday effect enhanced at resonance condition by up 5,000%. influence diameter array amplitude, width position...
Magnons, the quanta of oscillations localized electron spins, are a powerful tool for information transport and processing microwave signals. Owing to challenge energy efficient spin-wave control on small time- space scales, dynamic magnonic crystals have been proposed. Their distinct feature is possibility toggle off spatial periodicity magnetic waveguide that allows one realize unusual signal functions. The miniaturization circuits, reduction in consumption, fast operation important...

In this work, we investigate the structural and dynamic magnetic properties of yttrium iron garnet (YIG) films grown onto gadolinium gallium (GGG) substrates with thin platinum, iridium, gold spacer layers. Separation YIG film from GGG substrate by a metal strongly affects crystalline structure its damping. Despite presence defects, however, exhibit clear ferromagnetic resonance response. The ability to tune damping without substantial changes magnetization offers attractive prospects for...
An induced nonlinear phase shift of spin waves excited in an yttrium iron garnet film waveguide has been studied. Experiments were performed with two microwave magnonic signals, being operating and pumping waves, co-propagated at different frequencies. The results show that a up to 180° for the low-power wave is when increasing pump-wave power. A theory describing developed taking into account four-wave parametric coupling damping waves. observed phenomenon paves way elaborate types logic circuits.

We report spin-wave diffraction, caustic beam emission, and the formation of Talbot carpets in an yttrium iron garnet (YIG) film equipped with magnonic Fabry-Perot resonators. The resonator structures are created by patterning cobalt boron ($\mathrm{Co}$-$\mathrm{Fe}$-$\mathrm{B}$) nanostripes on YIG film. Small gaps $\mathrm{Co}$-$\mathrm{Fe}$-$\mathrm{B}$ generate a magnetic field profile within film, functioning as slit grating when resonators block incoming spin waves at specific...
