将金刚石对顶砧技术、基于同步加速器的红外和拉曼光谱以及晶格动力学计算与之前的磁性工作相结合,揭示了Co[N(CN)2]2的压力-温度相图。二阶结构边界收敛于涉及自旋态的关键活动区域,揭示了压力诱导的局部晶格畸变如何触发这种量子材料中的铁磁→反铁磁转变。
Diamond anvil cell techniques, synchrotron-based infrared and Raman spectroscopies, and lattice dynamics calculations are combined with prior magnetic property work to reveal the pressure-temperature phase diagram of Co[N(CN)2]2. The second-order structural boundaries converge on key areas of activity involving the spin state exposing how the pressure-induced local lattice distortions trigger the ferromagnetic → antiferromagnetic transition in this quantum material.
