Fermi surface in BaNi${}_2$P${}_2$

Abstract

We report measurements of the de Haas-van Alphen (dHvA) oscillation and a band structure calculation for the pnictide superconductor BaNi${}_2$P${}_2$, which is isostructural to BaFe${}_2$As${}_2$, the mother compound of the iron-pnictide high-$T_c$ superconductor (Ba${}_{1-x}$K${}_x$)Fe${}_2$As${}_2$. Six dHvA-frequency branches with frequencies up to $\sim$8 kT were observed, and they are in excellent agreement with results of the band-structure calculation. The determined Fermi surface is large, enclosing about one electron and hole per formula unit, and three-dimensional. This is in contrast to the small two-dimensional Fermi surface expected for the iron-pnictide high-$T_c$ superconductors. The mass enhancement is about two.
