摘要

•The bicollinear ground state and the first-order phase transition of iron tellurium are well reproduced.•This work confirms the essential role of the spin–lattice coupling in explaining the magnetic properties of iron tellurium.•Specific magnetic excitation in strained iron tellurium is predicted.
