Magnetic Imaging Films.

The physical principles behind and various applications of magnetic imaging films are reviewed. The imaging films considered include, liquid and solidified nanoparticle films, thin solid films of bismuth-substituted ferrite garnets, and low- and high-coercivity amorphous films of rare earth-transition metal alloys (Gd-Co, Tb-Fe-Co). Preparation details and properties of uniaxial and planar magneto-optical indicator films (MOIF) are described and discussed alongside the analysis of the conditions for optimal magneto-optic (MO) contrast and experimental setup construction. In addition to this discussion a number of images demonstrating the application of MOIF are shown. [ABSTRACT FROM AUTHOR]
