| dc.description.abstractEn | CeAuAl which orders antiferromagnetically below TN=3.8 K is considered as a Kondo lattice. This intermetallic absorbs hydrogen at room temperature and at a pressure of 4.5 MPa. The newhydride CeAuAlH1.4(1) is stable in air and crystallises in a derivative structure of the hexagonal Ni2In-type with a=0.4427(1) nm and c=0.8467(1) nm as unit cell parameters. Moreover, it exhibits an antiferromagnetic order below TN=8.0(2) K and another magnetic transition at T1=3.0(2) K. The strong increase of the TN-temperature after the insertion of hydrogen in CeAuAl can be explained on the basis of the Doniach diagram; the increase of the unit cell volume induced by this insertion leads to a strong reduction of the influence of the Kondo effect. | |
