Nesting properties and anisotropy of the Fermi surface of LuNi${}_2$B${}_2$C

Abstract

The rare earth nickel borocarbides, with the generic formula $R$Ni${}_2$B${}_2$C, have recently been shown to display a rich variety of phenomena. Most striking has been the competition between, and even coexistence of, antiferromagnetism and superconductivity. We have measured the Fermi surface (FS) of LuNi${}_2$B${}_2$C, and shown that it possesses nesting features capable of explaining some of the phenomena experimentally observed. In particular, it had previously been conjectured that a particular sheet of FS is responsible for the modulated magnetic structures manifest in some of the series. We report the first direct experimental observation of this sheet.
