Exchange field enhanced upper critical field of the superconductivity in compressed antiferromagnetic EuTe2

Hualei Sun, Liang Qiu, Yifeng Han +17

We report high pressure studies on the C-type antiferromagnetic semiconductor EuTe2 up to 36.0 GPa. A structural transition from the I4/mcm to C2/m space group is identified at ~16…
