Abstract :
Magnetic properties of nanocrystalline Finemet ribbons with composition Fe73.5Cu1Nb3Si13.5 B9 are studied. Six different samples annealed for 1 hour at different temperatures are studied. Measurement of hysteresis loops and of relaxation, performed at temperature above the Curie point of the amorphous phase, are presented and discussed
