An opportunity of polar nanodomain formation in magnesium niobate thin films

A new technique of condensed matter research has been worked out. Nonelastic scattering of synchrotron radiation has been demonstrated to be usable in dynamic processes investigation of crystalline samples less than 100 nm thick. The procedure how to determine polar nanodomain parameters was proposed relying on experiments on diffraction of coherent (synchrotron) X-rays.
