The domain structure of BiFeO3 has been studied by transmission (4-800K) and reflection (300-1100K) microscopy. The rhombohedral phase transforms at ∼ 1083K to a non-cubic twinned phase, stable up to the decomposition at 1185K. Owing to a strong negative temperature shift (∼ -5. 9 cm-1K-1) of an absorption edge BiFeO3 turns opaque upon heating. At 15600cm-1 the 6Alg → 4T2g crystal field transition of Fe3+ occurs. The maximal spontaneous birefringence of the rhombohedral phase is very high (Δnγ, α = 0. 58 at Λ = 644nm and R. T.) and has been measured between 10 and 800K. |
