(a)–(c) SP-STM data of Fe/Ir(111) at different temperatures. For all images the same color scale and tunneling parameters were used (25×25  nm2, U=10  mV I=4  nA). The insets show the corresponding Fourier transforms. Black circles mark the contribution from the magnetic unit cell and gray circles the spots caused by the TAMR effect. (d) Line profiles along the direction indicated in (a)–(c).
