Abstract.

We present a neutron/synchrotron diffraction study of the orbital/charge ordering in Bi1/3Ca2/3MnO3. The compound presents a high degree of orthorhombicity, which has permitted us to identify different modulation wave vectors below TCO=300 K. In contrast with the single κ=1/3b* modulation proposed for La1/3Ca2/3MnO3, we report the observation of modulated domains with orientationally different commensurate wave vectors.
