Title |
Effect of solvent on the magnetic properties of the high-temperature V[TCNE]x molecule-based magnet |
Date |
2001 |
Description |
The different magnetic behaviors of the V[TCNE]x (TCNE=tetracyanoethylene) magnet prepared via the reaction of TCNE and V(CO)6 in CH2Cl2 and the solvent-free chemical vapor deposition (CVD) of TCNE and V(CO)6 onto a glass substrate were determined. It was shown that the presence of noncoordinating CH2Cl2 solvent molecules in the structure of the V[TCNE]x magnet does not substantially influence the magnetic ordering temperature; however, it creates additional structural disorder. This results in a correlated spin-glass behavior in low magnetic fields (H<100 Oe) at helium temperatures, small remanence, and vanishing coercive fields at room temperature. In contrast, the CVD-prepared film has increased structural order. Quantitatively, the degree of disorder was analyzed in the framework of the random magnetic anisotropy model. |
