Abstract
We report a coexistence of superconductivity and antiferromagnetism in five-layered compound HgBa2Ca4Cu5Oy (Hg-1245) with Tc=108 K, which is composed of two types of CuO 2 planes in a unit cell, three inner planes (IP) and two outer planes (OP). The Cu-NMR study has revealed that the OP undergoes a superconducting (SC) transition at Tc=108 K, whereas three underdoped IPs do an antiferromagnetic (AF) transition below TN∼60 K with the Cu moments of ∼ 0.3-0.4 μB. The metallic behavior observed at the IP well below TN points to a possibility that SC and AF order parameters coexist in a single CuO2 plane.
