NanoDMA and Nanoscratch Study of (Visco)-Elastic and Plastic Behaviors of a Thin Film of a Molecular Spin Crossover Complex.
We report a nanomechanical study of ca. 1 µm thick crystalline films of the molecular spin crossover (SCO) complex [Fe(HB(1,2,4-triazol-1-yl)3)2] across its thermal spin transition. Using quasi-static and dynamic (1-100 Hz) indentation techniques, a step-wise decrease in the modulus, E (from 9 ± 1 to 4.0 ± 0.5 GPa) and...
