M. Elghannami et al., INFLUENCE OF THE PREPARATION CONDITIONS ON THE MAGNETIC-PROPERTIES AND ELECTRICAL-RESISTIVITY OF FE73.5NB3CU1SI13.5B9 NANOCRYSTALLINE ALLOYS, Journal of magnetism and magnetic materials, 133(1-3), 1994, pp. 314-316
We present the magnetic properties and the resistivity values of a ser
ies of Fe73.5Nb3Cu1Si13.5B9 alloys quenched from different melting tem
peratures and using different spin velocities. Some nanocrystals with
a strong preferred orientation can be obtained directly from the melt
at low velocities. Such partially crystalline samples show a lower roo
m-temperature magnetostriction and resistivity than the amorphous ones
. They also show a retardation in the nanocrystallization process, but
the magnetic properties are poorer than those of the high-velocity sa
mples, both in the as-quenched state and after complete nanocrystalliz
ation.
