Abstract
The effect of heat treatment in applied magnetic field on the induced anisotropy and domain structure of (Fe1-xCox)79Mo8Cu1B12 (x = 0, 0.2, 0.5) nanocrystalline alloy system was investigated. A heat treatment of Codoped samples under the application of longitudinal magnetic field resulted in squared hysteresis loops characterized by very low coercive field values. Sheared loops with tunable slope and good field linearity were obtained after annealing in transverse magnetic field. Corresponding domain structure showed uniform character, oriented in the direction parallel or perpendicular to the ribbon axis after longitudinal or transverse magnetic field annealing, respectively. No effect of magnetic field annealing was found in Co-free sample. Correlations between Co-doping, the Curie temperature, and soft magnetic properties after magnetic field annealing are discussed.
