Scaling of the hysteretic magnetization in epitaxial Bi2Sr2CaCu2Ox films
Résumé
Scaling behaviour of the hysteretic magnetization, or associated with it the critical current density, of high quality epitaxial Bi2Sr2CaCu2Ox thin films was studied in the temperature range 5–45K and over three decades of the magnetic field H, 50G–50kG. Our study shows that there exists at least three different regions in the magnetic phase diagram with different scaling behaviour.
