Pb NMR was carried to get a detailed electronic state in the recently
reported ErPb2.Pb NMR results have revealed that most parts of ErPb2 a
re not the coexistent compound of the superconductivity and the antife
rromagnetic ordering, but a mixture of superconducting Pb (or Pb-rich)
region and an antiferromagnetic Er compound (or alloy). Some models o
n the structure in ErPb system are proposed.
