Weak ferromagnetism in the square-lattice Heisenberg $J_1$-$J_2$-$J_2^\prime$ model with easy-axis single-ion anisotropy

Motivated by recent experimental realizations of the Heisenberg model and two-dimensional altermagnetism using ultracold atoms in optical lattices, we systematically investigate the magnetic properties of the square-lattice Heisenberg $J_1$-$J_2$-$J_2^\prime$ model in the presence of easy-axis single-ion anisotropy $D$...
