摘要：
We have investigated the effect of columnar defects on the irreversibility line of 500 nm thick Eu-Ba-Cu-O films. The irradiation dose D of 230 MeV Au14+ ions is chosen as 2.3 x 10(15), 4.0 x 10(15), 6.0 x 10(15) and 8.0 x 10(15) ions/m(2). Both the critical temperature and the irreversibility line are affected systematically as D increases. The AC magnetic field has an amplitude mu(0)H(AC) of 0.1 mT and a frequency of 1 kHz while the DC magnetic field varies from 10(-4) to 1 T to track the irreversibility line under the identical criterion. We also compare the irreversibility line obtained by means of harmonic susceptibility with that determined from a pinch point in the M-H hysteresis curve, but they are not continuous to each other. It is found that the irreversibility line is strongly dependent on the J(c) criterion.
