Abstract
The magnetic behavior of the heavy fermion superconductor CeCoIn5 has been investigated. The low-field magnetization data show flux jumps in the mixed state of the superconducting phase in a restricted range of temperature. These flux jumps begin to disappear below 1.7 K, and are completely absent at 1.5 K. The magnetization loops are asymmetric, suggesting that surface and geometrical factors dominate the pinning in this system. The lower critical field (H-c1), obtained from the magnetization data, shows a linear temperature dependence and is anisotropic. The calculated penetration depth (lambda) is also anisotropic, which is consistent with the observation of an anisotropic superconducting gap in CeCoIn5. The critical currents, determined from the high field isothermal magnetization loops, are comparatively low (around 4x10(3) A cm(-2) at 1.6 K and 5 kOe).
