Similarity of magnetization and magnetic flux jumps evolution with the magnetic field direction relative to the plane of the superconducting niobium plate

Abstract

The magnetization M(H) of the superconducting niobium plate was measured for a series of angles α between the direction of the magnetic field and the plane of the sample. It was found that: (1) M(H) at α = 0° and α = 90° differ significantly; (2) the jumps in the magnetic flux, which are observed on M(H) at low temperatures, also differ significantly for α = 0° and α = 90°; (3) in a wide range of angles, the form of the dependences M(H) and the flux jumps, characteristic of α = 90°, are retained when the magnetic field deviates from the normal of the sample. The same is observed at a deviation from α = 0°, but in a smaller range of angles.
