Fig. 4: Simulation on spin fluctuations at Néel temperature in FePSe3.
From: Thermal evolution of spin excitations in honeycomb Ising antiferromagnetic FePSe3
a, b Zig-zag AF and FM clusters were used to simulate the spin fluctuation, respectively. c Experimental data at T = 110 K and E = [3,7] meV. d Calculated neutron intensity of the AF cluster in (a). e Experimental data at T = 110 K and E = [9,13] meV. f Calculated neutron intensity of the AF cluster (a) plus the FM cluster (b). The AF clusters and FM clusters are weighted with a ratio of 2:1 in (f). g Experimental data at T = 4 K and E = [14,18] meV. h Calculated neutron intensity at the same energy range as (g) by LSWT with parameters from Table 1.
