摘要
Torque and magnetization measurements in magnetic fields H up to 14 T were performed on CeCoIn5 single crystals. The amplitude of the paramagnetic torque shows an H-2.3 dependence in the mixed state and art H-2 dependence in the normal state. In addition, the mixed-state magnetizations for both H parallel to c and H parallel to ab axes show anomalous behavior after the subtraction of the corresponding paramagnetic contributions as linear extrapolations of the normal-state magnetization. These experimental results point towards a nonlinear paramagnetic magnetization in the mixed state of CeCoIn5, which is a result of the fact that both orbital and Pauli limiting effects dominate in the mixed state.
