The Gryromagnetic Factor of Conduction Electrons in Silver, Gold, Palladium, and Platinum

Abstract

(a), G. KURZ (a), H. WONN (a), V. V. NEMOSHKALENKO (b), and V. N. ANTONOV (b) For the gyromagnetic factor of the conduction electrons in metals a rigorous relativistic theory is developed generalizing Roth's theory, within which the Pauli formalism is used. In a first test calculation the g-shift is calculated for Ag, Au, Pd, and Pt in spherical approximation. The calculations yield a negative g-shift for Ag and a positive g-shift for Au, Pd, and Pt in agreement with the experimental results.

Conduction electron spin resonance of silver clusters in zeolite AgY

“…No precursor signal was observed in this case, but the g-value of 1.960 _+ 0.002 is close to both that found in zeolite AgA [7], and the g-value of 1.973 calculated by Schober et al [9]. No precursor signal was observed in this case, but the g-value of 1.960 _+ 0.002 is close to both that found in zeolite AgA [7], and the g-value of 1.973 calculated by Schober et al [9].…”

Manipulation of Dirac band curvature and momentum-dependent g factor in a kagome magnet

“…Bloch electrons in quantum solids also exhibit the Zeeman coupling to the magnetic field set by an effective g-factor that takes on a more complex functional form. In general, the g-factor can vary with the overall band structure, spin-orbit coupling, carrier concentration, and exchange and correlation effects [1][2][3][4][5] , and it is fully descried by a matrix that is a function of the crystal momentum k 2 . While the theoretical framework behind the g-factor momentum dependence was established around the middle of the last century 1,2,6,7 , the variations of the g-factor with momentum in ordinary metals and semiconductors are largely negligible.…”
