Spangolite’s unique geometrically frustrated maple-leaf lattice presents theoretical challenges in understanding its non-magnetic ground state and magnetic properties. Here, the authors propose a spatially anisotropic Heisenberg model, validated by tensor network calculations, revealing a non-trivially correlated dimer ground state and predicting magnetization plateaus, thereby resolving a long-standing puzzle in experimental observations.
