Magnon quantum condensation has the potential to bring new developments to quantum computers, which are limited by the ultra-low temperature environments, but requires the search for thermally stable materials. Although Fe monocrystals have superior thermal stability compared to conventional materials such as yttrium iron garnets, magnon condensation using cubic anisotropic materials is still not well understood. In our presentation, we analyze magnons excited in Fe monocrystals by time-resolved Brillouin light scattering spectroscopy and report on the magnon formation in cubic anisotropic materials.
