Landeau-Lifshitz theory

The Landaou-Lifshitz theory describes how the magnetic moment (or tiny magnetic fields inside materials) responds over time to changes in magnetic fields, especially at high frequencies. It provides equations that predict how magnetic materials absorb and dissipate energy when subjected to varying magnetic fields, explaining phenomena like magnetic damping and resonance. This theory helps engineers design better magnetic devices, such as transformers and magnetic storage, by understanding the dynamic behavior of magnetic materials under alternating or rapidly changing conditions.
