Abstract

Eu_1.5Ce_0.5RuSr₂Cu₂O ₁₀ is the first Cu-O based material in which superconductivity (SC) and ferromagnetism (FM) have been shown to coexist (T_C = 32 K, T_M = 122 K thus T_M > T_C). SC is confined to the CuO₂ planes, and the magnetic ordering is due to the Ru sublattice. Hole doping in the CuO₂ planes can be achieved with variation of oxygen or hydrogen concentrations. The effect of O is to increase T_C (up to 49 K) and T_M (up to 168 K). The effect of H is to suppress SC and enhance the FM properties (T_M increases to 225 K). In contrast to other HTSC materials, this effect is reversible: by depletion of hydrogen, SC is restored and T_M drops back to 122 K.
