N2 - We systematically studied the spin-lattice couplings in the CrF3 monolayer. Our study reveals that the spin exchange constants between the nearest neighbors are notably affected by these couplings. Specifically, the couplings arise predominantly from three distinct phonon modes, namely the covariant, rotation, and stretch of the Cr-F-Cr-F rhombus. By integrating out the phonon degrees of freedom, we derived an effective spin Hamiltonian featuring four-spin product terms, which yields a remarkably intricate magnetic phase diagram. Significantly, numerous plateau states characterized by fractional magnetizations, including 1/2, 1/3, 2/3, 1/4, 1/5, 5/8, 1/9, 2/9, and 3/11, emerge in the vicinity of the phase transition boundary separating ferromagnetic and antiferromagnetic states. These findings show the profound influence of spin-lattice couplings on magnetic properties near the magnetic phase boundaries.
