本文报道了利用新的高压同步加速器x射线发射光谱技术，观察到FeS中压力诱导的高自旋到低自旋的转变。低能卫星在Fe - KP发射谱中的消失证明了这一转变。此外，相变是可逆的，并且与从磷化锰样相到单斜相的结构相变密切相关。该研究为研究压力下材料的电子特性开辟了新的机会。[s0031 - 9007(99) 08946 - 2]。
We report the observation of the pressure-induced high-spin to low-spin transition in FeS using new high-pressure synchrotron x-ray emission spectroscopy techniques. The transition is evidenced by the disappearance of the low-energy satellite in the Fe KP emission spectrum of FeS. Moreover, the phase transition is reversible and closely related to the structural phase transition from a manganese phosphidelike phase to a monoclinic phase. The study opens new opportunities for investigating the electronic properties of materials under pressure. [S0031-9007(99)08946-2].
