Description

Resonant X-ray scattering experiments have been performed on a heterostructure comprising ferromagnetic (La0.7Ca0.3MnO3)100A and superconducting (YBa2Cu3O7-δ)100A blocks. These measurements have probed a superstructure with wavevector q=(0.50.50), originating from the distortion of the MnO6 octahedra responsible for the ferromagnetic state in the La0.7Ca0.3MnO3 blocks. An intriguing temperature dependence of the integrated intensities indicates the rotation of the distorted MnO6 octahedra with the onset of both ferromagnetic and superconducting order, correlated via SQUID magnetisation and resistivity measurements
