Disappearance of static magnetic order and evolution of spin fluctuations in Fe${}_{1+\delta }$Se${}_x$Te${}_{1-x}$

Zhijun Xu, Jinsheng Wen, Guangyong Xu +7

We report neutron scattering studies on static magnetic orders and spin excitations in the Fe-based chalcogenide system Fe${}_{1+\delta }$Se${}_x$Te${}_{1-x}$ with different Fe and Se compos…
