Abstract
We present an antiferromagnet composed of a Mn-verdazyl complex . An analysis of the magnetic behavior reveals that the strong antiferromagnetic intramolecular interaction between spins on and the verdazyl radical forms an hybrid spin below approximately 100 K. In the low-temperature regions, the magnetic susceptibility and the specific heat indicate a phase transition to the three-dimensional order of the = 2 system. Below the transition temperature, the magnetization curve exhibits a metamagnetic phase transition. From the analysis of electron spin resonance modes, we evaluate the on-site biaxial anisotropy responsible for the anisotropic magnetic behavior.
