Abstract
Thermal variation of magnetization and magnetostriction of CoMnB alloys with x = 10 and 20 is studied. λs/Î5/2 [[MATH]-1 (m)] is plotted vs. m2/Î5/2 [[MATH]-1 (m)] where m is the reduced magnetization : the origin of λs, is discussed ; for x = 10, annealing 1 hour at 580 K the as-quenched ribbon changes dramatically λs, from 3 to 27 x 10-8.
