Analysis of the current-voltage characteristics and transport critical current density of superconducting yba2cu3o7in the self-field approximation

The temperature and sample size (width, thickness, and cross-sectional area) dependences of the zero-field current-voltage characteristics and transport critical current density Jc of YBa2Cu307_^ have been studied by using the motion of the flux lines which depends on the pinning force Fp and the Lorentz forces FL. We have obtained analytical expressions for the sample size and temperature dependences of the critical current density and current-voltage characteristics, which are in reasonable agreement with most of the experimental data published previously. It has been shown that the viscous drag coefficient of the medium changes with temperature as i) = rj0[1 - (r/Tc)2]. We have also found that the pinning force Fp is proportional to [B(T)]3/£ which implies that the diameter of the spherical pinning centres is larger than the coherence length as in the case of conventional hard superconductors. © 1995 IOP Publishing Ltd.
