Abstract

We study the influence of irradiation with Pb and Xe ions on the magnetic properties of thin YBa₂Cu₃O_7-x films. Using analysis of scaled pinning force we found unidirectional magnetic anisotrophy in the case of Pb irradiation. For Xr irradiated samples, such anistrophy was not found. The irreversibility lines and their frequency dependencies vary with the type of defects and the direction of the external magnetic field.

Funding Information:
From these fits we find coo = 15.8, 77.3, 13.1, 25.2 kHz and U c = 0.26, 0.23, 0.07, 0.035 eV for samples U(0O), Xe45(0o), Pb45(0o), and Pb0(0°), respectively. Surprisingly, U c is quite low for Pb irradiated samples. This value depends strongly also on the angle between the external magnetic field and direction of the columnar defects. Our results show that Uo(T) at high temperatures barely changes in the case of the defects induced by Xe irradiation in comparison with unirradiated sample, but smears dramatically in the case of the columnar defects. We thank Y. Wolfus and L. Burlachkov for helpful discussion. This project has been supported by the DG XII, Commission of the European Communities, and the Israeli Ministry of Science and the Arts.
