Frustrated spin order and stripe fluctuations in FeSe
Frustrated spin order and stripe fluctuations in FeSe
Abstract The charge and spin dynamics of the structurally simplest iron-based superconductor, FeSe, may hold the key to understanding the physics of high temperature superconductors in general. Unlike the iron pnictides, FeSe lacks long range magnetic order in spite of a similar structural transition around 90 K. Here, we report …
