Abstract
We have measured the resistivity along c-axis Ïc(H, T) of DyNi2B2C with the applied magnetic field H perpendicular to c-axis for 0 kG < H < 4 kG and temperature range 2 K < T < 300 K. From these, the superconducting upper critical field HC2(T) curve of DyNi2B2C for the c-axis was constructed and our HC2(T) curve from Ïc(H, T) measurement has been compared with that from previous known Ïab(H, T) result. With additional magnetization isotherms M(H, T) for H â¥Â c and H â¥Â c-axis, the anisotropy in HC2(T) curves of the magnetic structure DyNi2N2C, which has the superconducting transition temperature TC is lower than the Néel temperatures TN, might be originated from the additional anisotropic magnetic Dy3+ sublattice.
