电-声相互作用对金属氢磁性的影响

The Effect of Eleetron - Phonon Interaetionon the Spontaneous Magnetizationof Metallic Hydrogen

本文运用Hirsch的自旋—极化铁磁理论,并考虑了电—声相互作用对单中心、双中心以及电子有效质量的修正后,讨论了金属氢在T=OK时的自发磁化强度随晶体的Wigner-Seitz半径r_(s)的变化。结果指出:金属氢的自发磁化强度m_(s)≠0的区域随参数P的增大而收缩,但m_(s)的值不一定比未考虑电—声相互作用时的值小。

Abstract In this paper, it is discussed that the spontaneous magnetization of metallic hydrogen at T = OK changes with Wigncr-Scitz radius rs using Hirsch's spin - polarization fcrromagnetism theory and concerning the correction of electron - phonon interaction for one - center and two - center intcracteon . Then, we point out that the areas of mj3=0 get narrow when p>1.20, but the m3 of ours are larger than those of Hirsch' s when X 1.5. This conclusion is different from that of Wu's.
