Gokhfeld, D. M. Tuning the peak effect in the Y1−xNdxBa2Cu3O7−δ compound [Текст] / D. M. Gokhfeld, D. A. Balaev, I. S. Yakimov, M. I. Petrov, S. V. Semenov // Ceramics International. — 2017. — Т. 43. — С. 9985-9991Аннотация:
Polycrystalline Y1−xNdxBa2Cu3O7−δ (x=0.02, 0.11, and 0.25) superconductors are synthesized. Nd atoms are uniformly distributed over grains. The magnetization loops of the samples have a pronounced second peak in a wide temperature range. The magnetization data are analyzed using the extended critical state model. It is found that the order-disorder transition of the vortex lattice is affected by doping with neodymium and temperature; the second-peak field and width decrease monotonically with increasing x value. The undoped polycrystalline YBa2Cu3O7−δ compound is assumed to exhibit the peak effect in higher magnetic fields.
