X-ray diffraction (XRD) patterns reveal a gradual formation of the orthorhombic phase and Bi14CrO24 impurity with increasing chromium concentration. The Riet- veld refinement and Raman scattering analysis confirm the structural transformation from the polar R3c to the anti-polar Pnam phases. The Cole-Cole plots show two relaxation regimes which are attributed to gain and grain boundary responses above room temperature. The slim magnetic hysteresis loops are observed in samples with x 1⁄4 0.02e0.08, while a robust loop with the coercivity field of Hc z 1200 Oe is observed for x 1⁄4 0.1 sample where the canted antiferromagnetic phase is significantly contributed to the total magnetization. This result approves that the cycloidal spin structure cannot be suppressed by Cr doping.Thi Anh Hoanhht@vnu.edu.vnPhong P.T.Thoan N.H.Thi Minh Hong Nguyenhongntm@vnu.edu.vnHao N.V.Ha L.T.Bach T.N.Thanh T.D.Xuan C.T.A.Quang N.V.Dang N.V.Tho P.T.
