Fig. 1: Fe/Rh films on Ir(111).
From: Nano-scale collinear multi-Q states driven by higher-order interactions
Overview SP-STM image (partially differentiated constant-current data) of about 0.3 atomic layers of Fe on about 0.5 atomic layers of Rh on Ir(111). Below is a side-view sketch, colored dots indicate a specific layer sequence. (Measurement parameters: U = +50 mV, I = 1 nA, B = −2 T, T = 4.2 K, Cr-bulk tip).
