Abstract

We present the magnetic and superconducting phase diagram of EuFe ₂As₂ for Bc and Bab. The antiferromagnetic phase of the Eu²⁺ moments is completely enclosed in the superconducting phase. The upper critical field vs. temperature curves exhibit strong concave curvatures, which can be explained by the Jaccarino-Peter compensation effect due to the antiferromagnetic exchange interaction between the Eu²⁺ moments and conduction electrons.
