| Popis: | In Fe[N(SiPh2Me)2]2 molecular magnet, an extraordinary B ≈ 92 T hyperfine field was found in the 5 K 57Fe Mossbauer spectrum under an external magnetic field of 0.1 T. This evidences the presence of an unquenched orbital angular moment at the central iron atom. Fe[N(SiPh2Me)2]2 complex is thus shown to represent a further example of low-coordinate iron complexes where quasi free-ion magnetism visualizes itself through an unquenched orbital moment. Magnetization measurements and hysteresis in magnetization indicated exchange coupling and nanosized magnetic units. |
