UPd2Al3

UPd₂Al₃ is a heavy-fermion superconductor with a hexagonal crystal structure and critical temperature T_c=2.0K that was discovered in 1991.^[1] Furthermore, UPd₂Al₃ orders antiferromagnetically at T_N=14K, and UPd₂Al₃ thus features the unusual behavior that this material, at temperatures below 2K, is simultaneously superconducting and magnetically ordered.^[2] Later experiments demonstrated that superconductivity in UPd₂Al₃ is magnetically mediated,^[3] and UPd₂Al₃ therefore serves as a prime example for non-phonon-mediated superconductors.
