  text: NiPS3 has attracted considerable attention, yet the origin of its intriguing
    magnetic behaviors remains elusive due to limited insight into its low-energy
    anisotropy. Here, high-field torque magnetometry measurements are performed, revealing
    a previously unrecognized anisotropic spin response that reflects interaction
    terms beyond the standard XY or XXZ models. In combination with relativistic density
    functional theory calculations and magnetic force response theory, an effective
    low-energy spin Hamiltonian is constructed, elucidating not only the observed
    anomalous magnetic behavior but also other recent experiments. Remarkably, the
    magnetic dipole interaction and the associated spin-flop transition play a crucial
    role in driving the deviation from two-dimensional spin alignment, providing direct
    insight into the underlying anisotropic energy hierarchy. The generalized Hamiltonian
    can serve as the important fundamental ground for future study, and our approach
    adopted here will hopefully be relevant to many other related material systems.
