Description
The quantum size effect plays a crucial role in the fundamental physics as well as technological applications in the two-dimensional materials. In our studies, we have investigated the quantum size effect on the antiferromagnetic 120$^\circ$ Néel state of monolayer Mn on Ag(111) by utilizing spin-polarized scanning tunneling microscopy (SP-STM). The typical area sizes of Mn nanoislands under investigation are ranged from 30 to 170 nm$^2$. The interplay between the area size, modulation of Néel state and magnetic field dependence have been discussed as a manifestation of the quantum size effect.
