dc.description.abstractEnCePtAl absorbs hydrogen up to a concentration of 1.1(1)H mol−1 at room temperature. The formation of this hydride CePtAlH1.1 that loses hydrogen in air corresponds to a plateau pressure of 0.08-0.1 MPa. Its absorption-desorption is practically reversible which can present a potential interest for applications (but only a few due to the high price of the material) around room temperature and normal pressure. Hydrogenation of CePtAl induces both: (i) a structural transition but the structure of the hydride is unknown at present; (ii) an increase of its ferromagnetic character; the hydride has a Curie temperature Tc=11.6(2) K twice greater than that determined for the initial intermetallic (i.e. 5.6(2) K).
