DOMAIN STRUCTURE REVERSIBLE RECONSTRUCTION AND CHANGING OF DOMAINS WIDTH IN FERRITE-GARNET FILMS CAUSED BY WATER MOLECULES ADSORPTION

摘要

Due to water molecules adsorption the reversible change of domains width and domain structure reconstruction in bismuth-doped ferrite-garnet thin films with perpendicular magnetic anisotropy was observed. The change of domains width was 15% in saturated water vapor at room temperature. The decrease of domains width is explained by the reduction of effective perpendicular magnetic anisotropy constant due to water molecules adsorption.
