| dc.description.abstractEn | The hydride NdCoSiH obtained by exposure at 523 K of the ternary antiferromagnet NdCoSi under a pressure of 4 MPa of hydrogen crystallizes in the tetragonal ZrCuSiAs-type structure where H atoms occupy the tetrahedral [Nd<sub>4</sub>] site. The hydrogenation induces an increase in the unit cell volume close to 6%. The investigation of NdCoSiH by magnetization measurements reveals its ferromagnetic behavior below <i>T</i><sub>C</sub> = 20.5(5) K. Neutron powder diffraction shows that the <i>T</i><sub>C</sub> temperature is associated with a ferromagnetic arrangement of the Nd moments (2.3(2) μ<sub>B</sub> at 1.5 K) parallel to the <i>c</i> axis as observed for NdFeSi. The magnetic properties, magnetic structure, and the value of the Nd ordered magnetic moment evidenced for NdCoSiH are discussed using both band structure calculations and a comparison with the behavior of NdCoSi and NdFeSi. | |
