| dc.description.abstract | YFO (YFeO3) target is used for deposition on GGG (Ga3Gd5O12) substrates with different directions: (001), (110) and (111) by PLD (Pulsed Laser Deposition). HRXRD characterization shows that high-quality epitaxial garnet phase is formed on GGG substrates. However, RSM results show that the off-stoichiometric YIG film on (111) GGG substrates can remain fully strained in plane with thickness from 23 nm to 74 nm; while the samples on (001) GGG substrates show different degrees of relaxation in-plane depending on film thickness. Magnetic characterization shows that the samples grown on (111) GGG substrates have saturation magnetization Ms~45 emu/cc, which is significantly smaller than standard YIG (~140 Ms~45/emu/cc). Furthermore, the Curie temperature of samples grown on (111) GGG is ~ 310K, in obvious contrast with standard YIG ~560K. | en_US |
