Phototunable Magnetism in Copper Octacyanomolybdate

Figure 2

Possible nonmagnetic [Γ𝐷̆(Γ)⊗𝑆̆⁰⊗𝑇̆⁰ and M𝐷̆(M)⊗𝑆̆⁰⊗𝑇̆⁰] and magnetic [Γ𝐷̆(Γ)⊗𝑆̆¹⊗𝑇̆¹ and M𝐷̆(M)⊗𝑆̆¹⊗𝑇̆¹] states, where varied circles and arrows represent oscillating electron and spin densities, respectively, and varied segments in the nonmagnetic and magnetic states describe oscillating bond orders and spin bond orders, respectively. They consist of paramagnetism (PM) and charge disproportionation (CDP) of full symmetry, charge density waves (CDWs) within the molybdenum and/or copper sublattices, a bond order wave (BOW), ferromagnetism (FM), antiferromagnetism (AFM) within the molybdenum and/or copper sublattices, and a spin bond order wave (SBOW).
