Research Abstract

CeCoIn_5 is a heavy fermion superconductor with the superconducting transition temperature T_c=2.3 K. Yb is divalent and hence nonmagnetic in isostructural YbCoIn_5.We fabricate artificial superlattices of heavy fermion superconductor CeCoIn_5 and normal metal YbCoIn_5.Superconductivity appears even in 3-1 unit cell thick CeCoIn_5 superlattice, while local inversion symmetry breaking occurs at the interface between CeCoIn_5 and YbCoIn_5 layers.
