“…The slow increase of B for 30 • < θ < 70 • means that the initial vortices are strongly pinned along the c-axis inhibiting the magnetic field from the subsequent production of vortices along the ab-plane. This is a vortex-cross flux effect where the initial vortices along the c-axis act as pinning agents [19]. To better understand this behavior we plot in Fig.…”

“…Two sets of pickup coils mounted in quadrature allowed us to measure both the longitudinal (M L ) and the transverse (M T ) components of the rotational magnetization (M rot ) relative to the fixed H applied parallel to the plane of the sample disk. Both the longitudinal and the transverse magnetization components (M L , M T ) lie in the horizontal plane of the circular-disk sample, which is rotated with the magnetometer assembly about the vertical axis of vibration [14,15]. However, since the demagnetization correction was extremely small, it could be neglected.…”

Rotational magnetization‐vector measurements have been performed on polycrystalline Y1Ba2Cu3O7—δ superconductors under various magnetic fields at 4.2 K. The experimental results show that the vortex‐flux density has three parts: a weak pinning part which stays at a fixed angle relative to the magnetic field, a strong pinning part which rotates rigidly with the sample and which has the same magnitude as the sample rotation, and an intermediate pinning part which rotates rigidly with the sample, but whose magnitude changes with the sample rotation. These results have been explained by using the strength distribution of the vortex pinning torque and the repulsive intervortex torque.
