| dc.description | For the first time the influence of irradiation-induced columnar defects (0.5 GeV I-ions) on flux line pinning in Bi-2212 crystals has been investigated by means of the high-resolution magneto-optical Faraday effect. By irradiating only a part of each sample, the local change in the flux pinning has been determined. Irradiated and nonirradiated parts have been investigated simultaneously under the same experimental conditions. At T = 5 K and μ<sub>0</sub>H<sub>ext</sub> = (0 ÷ 300) mT a large enhancement of j<sub>c, m</sub> is found in the irradiated region. The observation of the time dependence of the flux density distribution yields small values for the pinning potential U, supporting the model of two-dimensional pancake vortex pinning. |
