Editing Magnons (section)

=== Role in Magnetism ===
Magnons play a fundamental role in the behavior of [[Magnetism]]. In ferromagnetic materials, the spins of electrons tend to align in the same direction due to exchange interactions, leading to a net magnetic moment. When thermal energy or other disturbances cause some spins to flip or precess, magnons are generated, and these excitations can be analyzed to understand various magnetic properties such as:
* '''[[Magnetic Susceptibility]]''': The degree to which a material can be magnetized by an external magnetic field.
* '''[[Magnetic Resonance]]''': Magnons are key in the study of electron spin resonance (ESR) and ferromagnetic resonance (FMR), where the material's response to an oscillating magnetic field is measured.
* '''[[Spintronics]]''': Magnons are important in the field of spintronics, where the spin of electrons, rather than their charge, is used to store and transmit information in devices.
