Disappearance of spiral spin order and field induced spin reorientation transition in Fe1−xCrxVO

An additional simultaneous magnetic ordering and magneto-capacitive behavior with dielectric relaxation besides multiferroicity in Fe 1−x Te x VO4

“…the width of the lines (Γ 1 -Γ 6 ) (especially for the outer lines) follows the mechanism like Γ 1 < Γ 6 , Γ 2 > Γ 5 , Γ 3 > Γ 4 indicates the persistence of an incommensurate spin cycloid structure (spiral) for all the samples at low temperature (5 K, below T N2 ) [7,69]. Recently, this type of asymmetric line broadening studies on Cr doped FeVO 4 compound have been reported elsewhere [70]. The observation of the increase in ratio of the area under the peaks 2 and 3 (A 23 ) with the applied magnetic field in MS at 5 K and 5 T suggests that the ordering is of antiferromagnetic in nature [71].…”
