Title: Competing magnetic phases and itinerant magnetic frustration in ${SrCo}_{2} {As}_{2}$

Abstract

Whereas magnetic frustration is usually associated with local-moment magnets in special geometric arrangements, here we show that ${SrCo}_{2} {As}_{2}$ is a candidate for frustrated itinerant magnetism. Using inelastic neutron scattering (INS), we determine that antiferromagnetic (AF) spin fluctuations develop in the square Co layers of ${SrCo}_{2} {As}_{2}$ below T ≈ 100 K centered at the stripe-type AF propagation vector of ($$\frac{1}{2}$$, $$\frac{1}{2}$$), and that their development is concomitant with a suppression of the uniform magnetic susceptibility determined via magnetization measurements. We interpret this switch in spectral weight as signaling a temperature-induced crossover from an instability towards FM ordering to an instability towards stripe-type AF ordering on cooling, and show findings from Monte-Carlo simulations for a J₁-J₂ Heisenberg model that illustrate how the crossover develops as a function of the frustration ratio –J₁/(2J₂). By putting our INS data on an absolute scale, we quantitatively compare them and our magnetization data to exact-diagonalization calculations for the J₁-J₂ model [N. Shannon et al., Eur. Phys. J. B 38, 599 (2004)], and show that the calculations predict a lower level of magnetic frustration than indicated by experiment. We trace this discrepancy to the large energy scale of the fluctuations (J_avg ≳ 75 meV), which, in addition to the steep dispersion, is more characteristic of itinerant magnetism.
