Competing magnetic phases and itinerant magnetic frustration in ${\mathrm{SrCo}}_{2}{\mathrm{As}}_{2}$
Abstract
Whereas magnetic frustration is usually associated with localmoment magnets in special geometric arrangements, here we show that ${\mathrm{SrCo}}_{2}{\mathrm{As}}_{2}$ 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 ${\mathrm{SrCo}}_{2}{\mathrm{As}}_{2}$ below T ≈ 100 K centered at the stripetype 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 temperatureinduced crossover from an instability towards FM ordering to an instability towards stripetype AF ordering on cooling, and show findings from MonteCarlo simulations for a J_{1}J_{2} Heisenberg model that illustrate how the crossover develops as a function of the frustration ratio –J_{1}/(2J_{2}). By putting our INS data on an absolute scale, we quantitatively compare them and our magnetization data to exactdiagonalization calculations for the J_{1}J_{2} 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.
