Enhanced nematic and antiferromagnetic phases in the spin-fermion model for strained iron pnictides

Enhanced nematic and antiferromagnetic phases in the spin-fermion model for strained iron pnictides

The effects of anisotropic superexchange and Fe–Fe hoppings on phase transitions in the undoped three-orbital spin-fermion model are investigated to understand the experimentally reported strain effect in BaFe _2 As _2 . Monte Carlo simulated phase diagrams show that both the collinear antiferromagn...
