Landau-Lifshitz Theory
Landau-Lifshitz theory describes how tiny magnetic moments within materials—think of them like microscopic bar magnets—interact and align in response to magnetic fields and internal forces. It explains the dynamic behavior of magnetization over time, including how it precesses and relaxes toward equilibrium. This theory is fundamental in understanding magnetic phenomena like ferromagnetism and the switching behavior in magnetic devices, providing a mathematical framework for predicting how magnetic materials respond to external influences and internal interactions.
