我们提出了一个反铁磁体组成的锰verdazyl配合物。磁行为分析表明，在100 K以下，自旋与Verdazyl自由基之间的强反铁磁分子内相互作用形成了杂化自旋。在低温区域，磁化率和比热表明相变的= 2系统的三维顺序。低于转变温度，磁化曲线表现出变磁相变。从电子自旋共振模式的分析，我们评估的各向异性磁行为的各向异性负责现场双轴。
We present anantiferromagnet composed of a Mn-verdazyl complex. An analysis of the magnetic behavior reveals that the strong antiferromagnetic intramolecular interaction between spins onand the verdazyl radical forms anhybrid 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.
