We explore the behavior of the order parameter and the magnetization of antiferromagnetic solids subjected to mutually parallel staggered and magnetic fields. The effective field theory analysis of the partition function is taken up to the two-loop level, where the magnon-magnon interaction comes into play. These interaction effects, however, are small. A phenomenon that comes rather unexpectedly is that the finite-temperature magnetization increases with temperature when the strengths of the staggered and magnetic field are held constant.
