Аннотация доклада:
Influence of reversible water molecules adsorption on domain structure of vismuth-doped ferrite-garnet thin films of composition (Bi,Lu)3(Fe,Ga)5O12 with perpendicular magnetic anisotropy was investigated by use of magneto-optical micromagnetometer and digital camera. For the first time reversible reconstruction of domain structure and decrease of domains width (d)was observed when introduction of water vapor into the cell with the sample took place. Maximal decrease of d was 15% for water vapor pressure p=1.8 kPa, which equal to saturated water vapor pressure for room temperature.
