Fig. 3: Spin excitations in FePSe3 at different temperatures.
From: Thermal evolution of spin excitations in honeycomb Ising antiferromagnetic FePSe3

Spin excitations in FePSe3 in (a) 101 K, (b) 107 K, (c) 110 K, (d) 113 K, and (e) 125 K. f A constant-E cut of the intensity in (a–e) with E integrated between 4 and 6 meV. The incident neutron energy used here is Ei = 35 meV. All error bars indicate one standard deviation.
