In this paper, the spin dependence of the quasiparticle masses on the two small ellipsoidal Fermi surface sheets of CeRu 2 Si 2 via the dHvA effect was measured.Abstract:
We have measured the spin dependence of the quasiparticle masses on the two small ellipsoidal Fermi surface sheets of CeRu 2 Si 2 via the dHvA effect. The field variation of the effective masses above the metamagnetic transition was obtained for the β ′ and γ ′ oscillations. We find that m ↓ * ( β ′ ) ≈ 5 m ↑ * ( β ′ ) , m ↓ * ( γ ′ ) ≈ 3 m ↑ * ( γ ′ ) .read more

TL;DR: In this paper, the de Haas-van Alphen effect was used to study the evolution of spin dependence of the effective mass in CeIn 3 and CeRu 2 (Si 1-x Ge x ) 2 by using physical and chemical pressures to control the relative strengths of the Kondo effect and the RKKY interaction.

Continuous evolution of the fermi surface of CeRu2Si2 across the metamagnetic transition
TL;DR: New, high resolution Hall effect and magnetoresistance measurements across the metamagnetic transition in the heavy fermion compound CeRu2Si2 force the notion that the transition is accompanied by an abrupt f-electron localization to be reconsidered.

TL;DR: In this article, the authors performed an extensive dHvA effect study of CeRu 2 Si 2 to gain more insight into the nature of the metamagnetic transition and confirmed the transition of the Fermi surfaces of the up and down spin electrons from those of the itinerant f electron below H m to those of localized f electron above H m.
