Inelastic neutron scattering measurements on the itinerant antiferromagnet CaCo2–yAs2 at a temperature of 8 K reveal two orthogonal planes of scattering perpendicular to the Co square lattice in reciprocal space, demonstrating the presence of effective one-dimensional spin interactions. Here, these results are shown to arise from near-perfect bond frustration within the J1–J2 Heisenberg model on a square lattice with ferromagnetic J1 and hence indicate that the extensive previous experimental and theoretical study of the J1–J2 Heisenberg model on local-moment square spin lattices should be expanded to include itinerant spin systems.
