Abstract

Induced current densities js(T,B) were measured in a wide temperature (5 ≤T≤ 90 K) and field range (0 ≤μ0Ha≤7 T) on single crystals of NdBa2Cu3O7-δ using a superconducting quantum interference device magnetometer. The samples exhibit the fishtail or peak effect at temperatures above 30 K. In a small temperature window between 50 and 74 K, three peaks are seen in the js(T,μ0Ha) curves. The temperature and field behavior of the induced current densities is analyzed using a model describing a magnetization curve as composed of two independent contributions at low and high fields. By means of this analysis, it is demonstrated that the third peak corresponds to the fishtail peak, whereas the position of the second peak is practically independent of temperature. It is shown that the appearance of the second peak is due to the large values of the position of the fishtail peak.
