Abstract: Correlation beyond entanglement is a subject of interest in quantum information. Here we showed the existence of quantum correlation without entanglement in Heisenberg XYZ spin model with external magnetic field, using different versions of measurement-induced nonlocality. Maximally entangled states are shown to possess maximum correlation.
