Comment on "Two-Dimensional Ising Spin Glasses with Nonzero Ordering Temperatures" by Lemke and Campbell [Phys. Rev. Lett. 76, 4616 (1996)]

Given the recent interest in inducing a finite-temperature spin-glass transition in quasi-planar topologies, we have performed large-scale Monte Carlo simulations of a two-dimensional square-lattice bimodal spin glass with next-nearest ferromagnetic interactions claimed to exhibit a finite-temperature spin-glass state for a particular relative strength of the next-nearest interactions [Phys. Rev. Lett. 76, 4616 (1996)]. Our results show that the system is in a paramagnetic state, despite zero-temperature simulations suggesting the existence of a finite-temperature spin-glass state. Therefore, deducing the finite-temperature behavior from zero-temperature simulations can be dangerous.
