Magnetoresistances (MR) of amorphous ribbons of Fe86Zr7Cu1B6 have been inve
stigated on the nanocrystallization by direct DC Joule heating. 3-D road ma
p of these samples was illustrated by the crystal sizes, coercivities and m
agnetizations, started from as-cast to the total annealing. The largest neg
ative MR of 0.5% was found for this system at T = 10 K. (C) 1999 Elsevier S
