| 中文摘要 | The effects of pressure and hydrogenation, the former causes a lattice contraction while the latter causes an expansion of the sample, have been systematically studied for LaFe(13-x)Si(x) (x=1.3-2.1). It is found that the typical change of the Curie temperature is similar to 150 K when similar to 1.6 H/f.u. is absorbed and similar to-106 K as the pressure sweeps from 0 to 1 GPa. One of the most remarkable results of the present work is the presence of a universal relation between Curie temperature and phase volume. The former linearly grows with the increase of lattice constant (similar to 1510 K/A), irrespective of how the phase volume is modified. This result implies the exclusive dependence of the magnetic coupling in LaFe(13-x)Si(x) on the Fe-Fe distances and the interstitial hydrogen does not affect the electronic structure of the compounds.
