Influence of Co content on structural and magnetic properties of CoxFe84−xNb7B9 alloys

2003

Nanocrystallization of CoxFe84� xNb7B9 (x ¼ 17; 25, 33) alloys has been studied. Crystallization of specimens starts above 4501C. After annealing of specimens in the range 500–7001C, apart from amorphous component and BCC Fe-Co alloy, a non-magnetic component also appears, which is attributed to (Fe1� xCox)2Nb phase with a relative area of about 14%. Decrease of quadrupole splitting with annealing temperature indicates some possible ordering of the nonmagnetic phase. r 2002 Elsevier Science B.V. All rights reserved.
