Abstract
Effect of annealing (300-700 degrees C, Ih) and geometry on the magnetic pr operties of Fe73.4-xCu1Nb3.1Si13.4 + xB9.1 (x = 1.1 and 1.6) glass-coated m icrowires has been investigated. The sensibility of coercivity to the geome try is attributed to the internal stresses. The evolution of the coercivity with the annealing temperature exhibits some peculiarities compared with t he classical FINEMET ribbon, especially in the temperature range of 400-500 degrees C (first stage of crystallization), showing also a remarkable depe ndence on the geometry.
