Cel Polarised Neutron Reflection (PNR) will be used to determine the magnetic moment per atom in thin magnetic films. Neutron reflectometry offers the unique possibility to study the spatial distribution of the magnetic moments, or of a decaying magnetic field, in addition to the nuclear scattering density profile. This technique can be exploited on the spectrometer of polarised neutrons SPN at the pulsed high flux reactor at Dubna, Russia. The application to thin High Temperature Superconductor Films (HTc-Films) will be pursued. The variation of the penetration depth profile as a function of the distance from the surface will be deduced. Furthermore magnetic flux lines appear in the HTc film at the critical external magnetic field, when there is no more complete screening of the magnetic field from the superconductor. This project will prove for the first time the existence of these flux lines in HTc-Films by using PNR. The Interface Magnetisation of ultra-thin magnetic sandwich structures will be determined by PNR. New magnetic features arise from the breakdown of the three dimensional crystal symmetry in ultra-thin films or at interfaces like enhanced or reduced magnetic moments with respect to the bulk moments. In addition effects at the interface between two magnetic materials (magnetic coupling behaviour) or between a magnetic and a non-magnetic material (induced magnetic moments) will be investigated.
