Ferromagnetic Resonance and Elastic Vibrations in Epitaxial Yttrium Iron Garnet Films

Magnetization dynamics affected by phonon pumping

“…(g) The obtained magnetoelastic coupling strength g me shows characteristic oscillations. [4,29,30]. These experiments revealed coherent hybridization of the (uniform) Kittel magnon with standing sound waves extended over the whole sample.…”

“…The study of magnon-phonon interactions in high-quality magnets has a long history [14][15][16][17][18][19][20][21]. The arrival of crystal growth techniques, strongly improved microwave technology, and discovery of new phenomena such as the spin Seebeck effect led to a revival of the subject in the past few years, with emphasis on ultrathin films and heterostructures [4,6,[22][23][24][25][26][27][28][29][30].…”

Magnetization dynamics affected by phonon pumping

“…Phonon pumping has been experimentally observed in the ferromagnetic resonance of YIG films on GGG substrates [4,29,30]. These experiments revealed coherent hybridization of the (uniform) Kittel magnon with standing sound waves extended over the whole sample.…”

“…where c t = 3570 m s −1 is the transverse sound velocity of GGG [36]. These are the anticrossings of the FMR dispersion with field-independent standing acous-tic shear wave modes across the full YIG/GGG layer stack [4,29,30,37,38]. In Fig.…”
