Spin waves are the elementary excitations of magnetic materials. They are interesting because of their rich physics and potential role in low-dissipation information technology. To better understand spin-wave transport and explore new ways to control it, this thesis focuses on developing magnetic-imaging techniques based on the single spin of the nitrogen-vacancy (NV) defect in diamond that detects spin waves via their magnetic stray fields. These fields decay evanescently on the scale of the spin wavelength. By using NV centres embedded in an atomic force microscope probe that provides nanometre NV-sample proximity, we achieve sensitivity to nanoscale spin waves.
