Abstract

Short-range antiferromagnetic (speromagnetic) behavior was observed for amorphous BiFeO₃ by static magnetic measurements, ac susceptibility (χ_ac) measurement, and ⁵⁷Fe Mössbauer spectra measurements. The magnetic behavior is classified into three temperature ranges: (i) paramagnet for T≳220 K; (ii) local clustering of spins for 20 K<T<220 K; and (iii) speromagnet in which all spins are frozen into random directions for T<20 K. In the spin freezing state the magnetization shows irreversibility and the χ_ac-T curve has a cusp. The variation of the spin freezing temperature against measuring magnetic field and measuring frequency indicate that the speromagnetic order is very similar to that of spin glass.
