The Heisenberg Model is a theoretical framework used in physics to describe magnetic systems, particularly in the study of ferromagnetism. It is based on the principles of quantum mechanics and was developed by physicist Werner Heisenberg. The model represents spins of particles on a lattice, where each spin interacts with its neighbors, leading to collective magnetic behavior. In the Heisenberg Model, the interactions between spins can be characterized as either ferromagnetic or antiferromagnetic. The model helps researchers understand phase transitions and critical phenomena in materials. It is a fundamental concept in condensed matter physics and has applications in studying various magnetic materials and phenomena.
