| Outline of Final Research Achievements |
In order to realize ferromagnetic resonance using a scanning tunneling microscope, we have introduced microwaves into existing equipment and have succeeded in detecting high-frequency waves at the probe-sample gap and in maintaining constant intensity during the sweep of the frequency by feedback control. We have also carefully examined the sample conditions required for ferromagnetic resonance based on numerical simulations, and found that systems with low magnetic anisotropy are suitable for our experimental conditions. As a system with low magnetic anisotropy, we focused on van der Waals magnets and succeeded in fabricating monolayer films of van der Waals magnets. We have also started development of spin-polarized potentiometry to detect resonance by spin current detection instead of spin polarization by the resonance, and confirmed that it works under ultrahigh vacuum and at low temperatures.
