Fig. 3: Parameter relationships with HDMI.

From: Experimental observation of the correlation between the interfacial Dzyaloshinskii–Moriya interaction and work function in metallic magnetic trilayers

Fig. 3

a Work function, W; b electronegativity, χ; and c SOC constant, ξ, as functions of HDMI for Pt/Co/X samples with different X values, as denoted in the figure. In each plot, HDMI was determined using the ε measurement from the data shown in Fig. 2, Wmea (red symbols) is the measurement work function, and Wref (black symbols), χ, and ξ are the literature values from refs. 33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56. The error bars for HDMI correspond to the experimental accuracy determined from several repeated measurements. The error bars for Wmea and Wref were obtained from measurement error and from the standard deviation of several different values from references
