The broad feature along the horizontal axis in the neutron reflectometry data at T = 7 K indicates the development of in‐plane magnetic correlations in the artificial honeycomb lattice (Figure 2). In order to further understand the underlying magnetic structure, experimental data is compared to the numerically simulated patterns for theoretically predicted magnetic phases, namely paramagnetic state as well as spin ice (ice‐1), charge ordered configuration (ice‐2) and spin solid states, all depicted in Figure 3 . The different magnetic states were simulated in our Distorted Wave Born Approximation (DWBA) model (see the Experimental Section for more information).29, 30 As shown in the lower panel of Figure 2, the off‐specular scattering increases with the amount of spin–spin correlation in the system. Although the difference between ice‐2 (magnetic charge ordered state) and spin solid is small, a reasonable agreement with the experimental data is obtained for the spin solid state. The spin solid state is modeled by arranging the vortex loops of opposite chiralities in an alternating order, as described above. The simulated patterns indeed exhibit broad bands of diffuse scattering along the x‐axis, as observed in the experimental data (also see the Supporting Information for detail about the modeling). We note that the interelemental energy in the newly designed artificial honeycomb lattice is ≈12 K. This is the characteristic energy necessary for a magnetic charge ordered state to develop, followed by the spin solid state as T → 0 K. Therefore, the observed increase in intensity is consistent with the expected behavior in our sample.
