DC magnetization measurements on (formula presented) reveal a first-order phase transition at (formula presented) for both (formula presented) and c axes in the isothermal magnetization (formula presented) below 0.7 K, indicating a strong Pauli paramagnetic suppression in the even-parity pairing. (formula presented) in the normal state above (formula presented) exhibits non-Fermi-liquid behavior down to 150 mK, implying the existence of antiferromagnetic fluctuations behind the unconventional superconductivity. We observed an unusual peak effect for (formula presented) in fields 5-30 kOe below (formula presented) whose anomalous temperature dependence cannot be simply explained by ordinary mechanisms.
