Magnetic and structural properties of epitaxial Er-substituted yttrium iron garnet films grown by pulsed laser deposition

Lukas Flajsman, Lars Peeters, Armi Kosunen +3

Er-substituted yttrium iron garnet (Er:YIG) holds the potential of combining the low magnetic damping of YIG with the telecom-band optical transitions of ${\text{Er}}^{3+}$ ions, mak…
