Abstract

We report measurements of the Fermi surface (FS) of the ternary phosphide SrFe $_2$ P $_2$ using the de Haas-van Alphen effect. The calculated FS of this compound is very similar to SrFe $_2$ As $_2$ , the parent compound of the high temperature superconductors. Our data show that the Fermi surface is composed of two electron and two hole sheets in agreement with bandstructure calculations. Several of the sheets show strong c-axis warping emphasizing the importance of three-dimensionality in the non-magnetic state of the ternary pnictides. We find that the electron and hole pockets have a different topology, implying that this material does not satisfy a nesting condition.
