Conduction-electron Zeeman splitting on theX-pocket holes in platinum

Abstract

The conduction-electron Zeeman splitting on the X-pocket holes in platinum has been investigated, with the use of the de Haasvan Alphen technique. The amplitude for the fundamental and second harmonic has been studied in the (100) and (110) planes. Two spin-splitting-zero contours on the second harmonic have been mapped out. A complete picture of the variation of the g, factor over the X pocket has been achieved, and its absolute value was found to range from 0.5 to 3.5.

Zeeman splitting in Pd and Pt calculated from self-consistent band structure including an external magnetic field

“…6, is in general too small. However, the agreement with experiment [7] with respect to anisotropic behavior is better than in Ref. [11].…”

“…In the alkali metals [1] the Zeeman splitting is found to be isotropic, but the g factor deviates from the free-electron value of 2. On the other hand, in Rh [2], Pd [3,4], Ir [5], and Pt [6,7] the cyclotron-orbit g factor (g c ) is found to be strongly anisotropic, and it is also known that in Pd and Pt the average g factor is large. The g c factor in the noble metals [8] also shows a strong anisotropy.…”
