Abstract

Several types of magnetooptical (MO) media, possessing "memory" effect are discussed for the purpose of thermal sensing. These are high coercive garnet films, trad.itionaly used. for therrnoxnagnetic re- cording, films with configurational phase transitions between dife- rent types of the domain structure produced by local heating and films with artifially formed pixel arrays. It's shown that structures of the latter type are most suitable for thermal sensing.
