Figure 2. Orbital magnetic moment for atom #1 of trimers on Cu(111).

Figure 2

(a) Fe #1 in Fe trimer: variation of the z-component of the orbital moment, mz, with the direction of the spin moment, for the ferromagnetic (F), chiral right- (R) and left-handed (L) magnetic structures (black, red and blue curves, respectively). The green curve shows the average of the data for the chiral structures. (b) Fe #1 in Fe trimer: difference between the orbital moments for the two chiral magnetic structures including spin–orbit coupling (SOC), and orbital moment for the R structure excluding SOC. (cf) Nonvanishing components of the orbital moment for atom #1 in Cr, Mn, Fe and Co trimers, respectively, computed excluding the SOC, in the R structure.
