Electronic Structure of LaSb_2
Abstract
LaSb2 is a nonmagnetic material that exhibits a large linear magnetoresistance. We have calculated its electronic structure using a full potential LAPW GGA density functional method including the spin-orbit interaction. We find that the Fermi surface consists of both two dimensional sheets and three dimensional bands. Our results are consistent with recent dHvA measurements^1. We discuss the possibility of CDW formation based on nesting of the sheets as well as compare with photoemission^2 and neutron scattering. ^1 R.G. Goodrich et al, submitted to Phys Rev B. ^2 A. I.
