TITLE:

MANUFACTURE OF NANOSTRUCTURES IN YTTRIUM IRON GARNET FILM ON SILICON SUBSTRATE FOR THE STUDY  SPINTRONICS  PHENOMENA

KEY WORDS:

YIG, MOD, EBL, FIB.

PAGES: 136
BIG AREA: Ciências Exatas e da Terra
AREA: Física
SUMMARY:

The general objective of this work is to manufacture quality nanostructured YIG films for the study of spintronics phenomena. Specifically Obtain YIG films by the MOD wet chemical method, with sufficient quality for the study of spintronics phenomena. Also make a detailed structural study of each system using High Resolution Electron Microscopy (HREM) to verify the effects of surface disorder on the magnetic properties in nanometric systems manufactured by us. Manufacture slits and guides on the previously manufactured YIG films, from a nanomachining process by IBL in FIB to study the dispersion of spin wave dispersion dynamics. To produce arrays of elongated square, circular, rectangular nanostructures in YIG films on Si (100) by EBL and IBL processes to study spintronic
phenomena observed in films obtained by conventional techniques. Using FIB and EBL techniques to form hybrid structures made of YIG and platinum films to simulate spintronic effects resulting in hybrid spintronic devices.
