| Abstract: | The behavior of a magnetic flux in a ceramic high-temperature superconductor with rotation of a magnetic field through a specified
angle has been investigated using polarized neutrons. Two models of penetration of a weak magnetic field into a granular superconductor
have been discussed. Based on the obtained distributions of the rotation angle and the magnitude of the magnetic field inside
the sample, the choice is made in favor of one of these models. |
