    "abstract": "We show that magnetic susceptibility can reveal spin entanglement between\nindividual constituents of a solid, while magnetisation describes their local\nproperties. We then show that these two thermodynamical quantities satisfy\ncomplementary relation in the quantum-mechanical sense. It describes sharing of\n(quantum) information in the solid between spin entanglement and local\nproperties of its individual constituents. Magnetic susceptibility is shown to\nbe a macroscopic spin entanglement witness that can be applied without complete\nknowledge of the specific model (Hamiltonian) of the solid.",
