Magnetostriction of metals with small Fermi-surface pockets: Case of the topologically trivial semimetal LuAs

Abstract

We develop a theory of the magnetostriction for metals with small charge-carrier pockets of their Fermi surfaces. As an example, we consider LuAs that has a cubic crystal structure. The theory quite well describes the known experimental data on the magnetostriction of this metal. The obtained results also clearly demonstrate that the dilatometry can be used for detecting tiny Fermi-surface pockets that are not discerned by traditional methods based on investigations of the Shubnikov--de Haas and de Haas--van Alphen effects.
