Superconducting Nd(1−x)Eu(x)NiO(2) thin films using in situ synthesis

We report on superconductivity in Nd(1−x)Eu(x)NiO(2) using Eu as a 4f dopant of the parent NdNiO(2) infinite-layer compound. We use an all–in situ molecular beam epitaxy reduction process to achieve the superconducting phase, providing an alternate method to the ex situ CaH(2) reduction process to i...

description We report on superconductivity in Nd(1−x)Eu(x)NiO(2) using Eu as a 4f dopant of the parent NdNiO(2) infinite-layer compound. We use an all–in situ molecular beam epitaxy reduction process to achieve the superconducting phase, providing an alternate method to the ex situ CaH(2) reduction process to induce superconductivity in the infinite-layer nickelates. The Nd(1−x)Eu(x)NiO(2) samples exhibit a step-terrace structure on their surfaces, have a T(c) onset of 21 K at x = 0.25, and have a large upper critical field that may be related to Eu 4f doping.
