N2 - We studied the superconducting properties of Pd hydride and deuteride prepared by a low temperature absorption method using in situ magnetization measurements down to T = 0.5 K. The absorption was performed under hydrogen (H2) or deuterium (D2) gas atmosphere at T = 200 K, where the gas pressure and magnetization were monitored simultaneously. From the pressure change caused by the absorption of H (D) in Pd sample, the H (D) content was determined to be 0.82 (0.79). The superconducting state was observed below T ~ 1.3K for the both systems. This state was investigated through precise magnetization measurements. The results suggest that H or D atoms are absorbed uniformly over the whole sample.
