Magnon condensates can be generated at room temperature, which has potential applications in quantum computation. For the development of magnon-based quantum devices, it is important to understand the generation process of magnon condensations in wavevector space in nanoscopic samples. In this study, we generated magnon condensates in a nanoscale waveguide using micromagnetic simulation and analysed the magnon condensation process in wavevector space using a three-dimensional discrete Fourier transform.
