Resumen en inglés
The ternary silicide CeNiSi, which crystallises in the tetragonal LaPtSi-type structure (a=4.070(2) Å, c=14.030(5) Å), absorbs hydrogen at P(H2)=2 MPa and T=393 K to form the stable hydride CeNiSiH0.8(1). The hydrogenation ...Leer más >
The ternary silicide CeNiSi, which crystallises in the tetragonal LaPtSi-type structure (a=4.070(2) Å, c=14.030(5) Å), absorbs hydrogen at P(H2)=2 MPa and T=393 K to form the stable hydride CeNiSiH0.8(1). The hydrogenation induces (i) an anisotropic variation of the unit cell parameters (a=4.040(1) Å and c=14.253(4) Å) without significant increase of the unit cell volume (+0.1%) and (ii) a strong increase of the Kondo interaction in comparison with the initial ternary silicide...< Leer menos
