Abstract

The weak magnetism of bismuth ferrites Bi_1-x Dy_x FeO₃ with x=0.0 to 0.40 is studied via the electron spin resonance (ESR) of X-band (9.53 GHz) at various temperatures. The g-factor of pure BiFeO₃ is 2.0, which originates from its cycloidal spin structure; while for the doped Bi_1-x Dy_x FeO₃ samples with x>0.10, ESR spectra reveal a second phase with a different g-factor around 1, which is attributed to the homogeneous magnetized phase of Bi_1-x Dy_x FeO₃. The temperature dependent ESR data further suggest a picture of the doping-induced transformation from cycloidal to canted antiferromagnetic state.
