Coupled spin dynamics in epitaxial trilayer heterostructures of ferrimagnetic garnet

A. Del Giacco, M. J. Gross, O. Wojewoda +9

The magnetization dynamics of an all-garnet trilayer consisting of Y3Fe5O12/Y3Fe3Al2O12/Y3Fe5O12 (YIG/YIAG/YIG) is analysed. The two magnetic YIG layers, separated by a 4 nm thick…
