Popis: New cuprate compounds have been synthesized by Sequentially Imposed Molecular Beam Epitaxy on MgO(100) substrates. The composition of the films corresponds to Cah−1Cuh+1O2h with h= 3. We present X-ray diffraction measurements performed with synchrotron radiation on a four circles diffractometer. These films crystallize in an orthorhombic structure with a single orientation perpendicular to the substrate surface. The value ofa andb parameters are in agreement with the two-leg ladder structure of the Cu2O3 planes, also observed by HREM.
