!--[if gte mso 9]> Perovskites LnV0.5Fe0.5O3 (Ln = Y,La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho and Er) were synthesized by rapid solidificationfrom arc-melted samples and characterized by the study of their crystalstructure and hyperfine properties. These metastable solid solutionscrystallized in the Pbnm symmetry, with the iron and vanadium cations randomlydistributed in the transition metal octahedral sites. Depending on the lanthanidepresent at the A site of the perovskite, iron is present with two valences(i.e., Fe3+ and Fe2+). The volume of the unit cell for these perovskitesincreases linearly wi
