The dc susceptibility shows antiferromagnetic interactions between Fe3+ spins with a Curie-Weiss temperature of Θ = -50(1) K, followed by spin-glass-like freezing at Tf ≈ 2.8 K, suggesting significant spin frustration. Temperature-dependent EPR measurements confirm the antiferromagnetic coupling of Fe3+ spins at high temperatures, while a distinct divergence is observed at T ≈ 50 K. This behavior is associated with the formation of spin clusters providing two different energy scales for the magnetic interactions. The magnetic response of Mg2FeV3O11-x is similar to that of the Zn-analogue compound, though the observed differences of the implicated energy scales indicate that magnetic inhomogeneity depends on the extent of cation disorder.}, doi = {10.1016/j.jnoncrysol.2006.07.009}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-33749526838\&doi=10.1016\%2fj.jnoncrysol.2006.07.009\&partnerID=40\&md5=ef3b7a82ba81af523980f8cfc444b038}, author = {Guskos, N. and V.
