Abstract:

The intent of the study was to define those physical properties of magnetic bubble materials which need to be characterized, to investigate the known methods for making these characterization, and, finally, to recommend those characterization procedures which appear best at this time. Those material properties included in the study were Substrate and film composition - substrate and film lattice parameter - substrate and film defect identification and location - film thickness - film thickness variations - characteristic length and domain dimensions - saturation magnetization and magnetic fields - domain wall energy - domain wall dynamic properties - anisotropy - coercivity - magnetostriction coefficients - reorientation temperature - Neel temperature - compensation temperature - temperature variation of material parameters - thermal conductivity - refractive index - Faraday effect - Kerr effect - optical and magneto-optical absorption - electrical conductivity - photo conductivity.
