Summary: | Abstract
Quantum magnonics is an emerging research field, with great potential for applications in a magnon based quantum technologies, including quantum computing, processing and encoding information. Magnon correlation and quantum entanglement are the main concepts in many quantum technologies under development. Of particular interest is the magnon Bose condensation. The emerging current question is the applicability of quasi-classical Landau–Lifshitz–Gilbert equations to describe the coherent state of magnons. We performed micromagnetic modeling of the magnetization dynamics at a high angle of deviation in an inhomogeneous magnetic field. We have obtained solutions that are well coincided with the properties of experimentally observed magnon BEC states. This result will be needed for the calculation the properties of magnetic devices on the basis of quantum magnonics. |
