First-order magnetic and structural phase transitions in Fe${}_{1+y}$Se${}_x$Te${}_{1-x}$

Shiliang Li, Clarina de la Cruz, Q. Huang +8

We use bulk magnetic susceptibility, electronic specific heat, and neutron scattering to study structural and magnetic phase transitions in Fe${}_{1+y}$Se% ${}_x$Te${}_{1-x}$. Fe$_{1.068…
