Abstract
We present the first experimental realization of an ferromagnetic-antiferromagnetic (F-AF) alternating chain in a new Mn-verdazyl complex [Mn(hfac)](-Py-V) [hfac=1,1,1,5,5,5-hexafluoroacetylacetonate; -Py-V=3-(2-pyridyl)-1,5-diphenylverdazyl]. Through the molecular orbital calculation, magnetization, and ESR measurements, this compound is confirmed to form an F-AF alternating chain with Ising anisotropy below about 100 K. Furthermore, we find an anomalous change in magnetization at 1/4 of the saturation value, which is probably a manifestation of the quantum nature of the system.
