SCES insulator of Fe0.5Ni0.5WO4. (A) Schematic strategy of Fe cations in the NiWO4 crystal structure to modulate Coulombic repulsion. Difference in Coulombic repulsion between Ni–Ni and Ni–Fe. (B) XRD results of NiWO4 and Fe0.5Ni0.5WO4. (C) Raman spectroscopy results of NiWO4 and Fe0.5Ni0.5WO4. The plot on the right side is a description of the peak shifts for [WO3] symmetric, [WO3] asymmetric, and [NiO] symmetric vibration modes. (D) Temperature dependence magnetization curve under 0.01 T.
