Paper Abstract

Offered work describes the results of feature investigation of GdFe and TbFe films magnetic reversal by magneto-optical method. The electrical outline of magnetic field formation for pulsing hysteresigraph is described. The opportunity of described hysteresigraph use for research of magnetization, demagnetization and alternating magnetization processes of films in external fields from 10 to 6000 Oe is shown. The examples of analysis of films magnetic structures on magneto-optical loop kind of hystersis are adduced. The turn of magnetizations both magnetic subsystems in GdFe films along external magnetic field was observed. The opportunity and conditions of films reversible alternating magnetization realization without change of magnetic field direction is shown. The opportunity of this phenomenon use for creation of thermo-magnetic record carriers with direct rewriting of information at constant external magnetic field is shown.
