Description
Summary:The distribution of magnetic induction vector B in HTSC ceramics YBaCuO in rotating external magnetic field has been studied both theoretically and experimentally using 3D neutron polarization analysis. It was demonstrated that the vector B changes both in value and direction. Transverse and longitudinal currents with respect to the local field direction are evaluated from the first principles using Maxwell equations and experimental data. Their behaviour is analysed.
