Abstract: The paper refers to magnetic properties of the (Fe80Nb6B14)1􀀀xTbx (x = 0:06 and x = 0:08) bulk nanocrystalline alloys prepared using the vacuum suction casting technique. The samples were in the form of rods with diameters of d = 1:5 mm, 1 mm and 0.5 mm. It was shown that for the alloys with x = 0:08 the signi cant magnetic hardening with the decrease of sample diameter was observed. For d = 0:5 mm the coercive eld equals 2.46 T and the maximum energy product jJHjmax = 77:2 kJ/m3.
