The magnetic properties of C14 Laves-phase Zr(FexCr1-x)2 (0.7 ≤ x ≤ 0.85) alloys have been investigated. Arrott plots showed evidence of ferromagnetic ordering for alloys with x > 0.7 but not for x = 0.7. Zero field cooling/field cooling magnetization and Mössbauer spectroscopy data indicated spin-glass-like freezing for the sample with x = 0.7 and a reentrant spin-glass behavior for samples with x > 0.7. Dynamical behavior of the spin-glass sample (x = 0.7) was studied by means of AC susceptibility. Two critical lines described by |Tf(H) -T(0)| ∼ H2/δ were obtained with δ = 4.4 and 2.5, respectively. © 2001 Elsevier Science B.V. All rights reserved.
