Abstract We show how a quantum state in microwave cavity mode can be transferred to and stored phononic via an intermediate magnon magnomechanical system. For this we consider ferrimagnetic yttrium iron garnet (YIG) sphere inserted cavity, where the modes are coupled magnetic-dipole interaction phonon YIG magnetostrictive forces. By modulating detunings driving of time, stimulated Raman adiabat...

We report an observation of a giant magneto-optical (MO) effect quadratic in magnetization (Cotton-Mouton effect) 50 nm thick layer yttrium-iron garnet (YIG). By combined theoretical and experimental approach, we managed to quantify both linear MO effects the studied material. show that signal thin YIG film can exceed response, reaching values 450 \ensuremath{\mu}rad are comparable with Heusler...

We investigate the influence of magnon decays on nonequilibrium dynamics parametrically excited magnons in magnetic insulator yttrium-iron garnet (YIG). Our investigations are motivated by a recent experiment Noack et al. [Phys. Status Solidi B 256, 1900121 (2019)] where an enhancement spin-pumping effect YIG was observed near field strength via confluence become kinematically possible. To expl...

The spectroscopic g-factor of epitaxial thin film Yttrium Iron Garnet (YIG) has been studied using a combination ferromagnetic resonance spectroscopy and x-ray magnetic circular dichroism. values obtained by the two techniques are found, within experimental error, to be in agreement Kittel's original derivation for g-factor. For an insulating material with entirely Fe 3+ configuration, spin mix...

The nature of resistive switching in structures yttrium iron garnet-aluminum (YIG/Al) observed when the current direction is changed relative to YIG magnetization has been studied. It established that effect magnetic field rotated increases with an increase passed through structure and achieves 100 percent from superconducting normal state. magnitude depends on geometric factors, namely, ratio ...

Recent studies show that hybrid quantum systems based on magnonics provide a new and promising platform for generating macroscopic states involving large number of spins. Here we how to entangle two magnon modes in massive yttrium-iron-garnet (YIG) spheres using cavity optomagnonics, where magnons couple high-quality optical whispering gallery supported by the YIG sphere. The can be as 1 mm dia...

In this paper we present the development of a magnetic moment reference material for low moment magnetic samples. We first conducted an inter-laboratory comparison to determine the most useful sample dimensions and magnetic properties for common instruments such as vibrating sample magnetometers (VSM), SQUIDs, and alternating gradient field magnetometers. The samples were fabricated and then me...

Introduction: Magneto-optics (MO) technology is believed to be far more advanced in the former Soviet Union when compared to the US. This is evidenced by the existence of factories geared for the production of Yttrium Iron Garnet (YIG) wafers. The potential advantages to MO Crystal Technology over other magnetic sensing technologies are (1) light weight and compact construction, (2) low cost, a...

We characterize magnetic-field sensors based on the Faraday effect in ferrimagnetic iron garnets in terms of their sensitivity, speed, and directionality. Signal-to-noise measurements at 80 Hz on small (typically 5 mm diameter x 3 mm long) samples of yttrium iron garnet (YIG) yield noise equivalent magnetic fields of 10 nT /.JHz. Frequen~y response measurements exhibit virtually flat response t...
