| Abstract Scope |
Two spin states of spin cross-over complex make it a promising candidate material for several electronic devices and sensors. The spin states can be influenced by external stimuli such as temperature, light irradiation, and strain, which affect both magnetization and electrical conductivity. One promising spin cross-over material is [Fe(Htrz)2(trz)](BF4) which contains Fe2+ ions and triazole ligand. The spin structure of iron(II) triazole changes with temperature, and the transition is accompanied by strain. In this study, the electrical conductivity of iron(II) triazole was mapped to local deformation. Bruker Dimension Icon Atomic Force Microscope with PeakForce TUNA module was used to simultaneously deform the material and map the electrical conductivity. Different sized nanorods of iron(II) triazole were fabricated. It was found that the deformation-dependent conductivity can either be proportional or inversely proportional to the deformation depending upon the size of the nanorods. |
