Dipolar corrections to the static magnetic susceptibility of condensed ${}^3$He

Abstract

We examine the consequences of a recent model describing correlated zero-point polarization of the electronic cloud in solid ${}^3$He. This polarization arises from the highly anisotropic and correlated dynamic mixing of the $s$ and $p$ electronic levels ($\sim 1$%). The magnetic polarization introduces a small paramagnetic correction, of $1-0.1$%, to the static susceptibility of condensed ${}^3$He. This correction could explain recent measurements in liquid ${}^3$He.
