Disentangling anisotropy and exchange in Co(NCX)₂ (X = S, Se) chains via THz-EPR spectroscopy

Key Points

• To clarify how chalcogen substitution influences magnetic properties in cobalt(II) chain compounds.
• Used THz-EPR spectroscopy to analyze magnetic interactions and properties.
• Investigated two isostructural cobalt(II) chain compounds with different chalcogen ligands.
• Compared the effects of selenocyanate and thiocyanate ligands on magnetic behavior.
• Identified variations in anisotropy and exchange interactions between the two compounds.
• Demonstrated that the type of chalcogen significantly affects the magnetic properties.
• Revealed distinct magnetic behaviors based on ligand substitution in cobalt chains.
