A comparison of μSR and thermopower in Hg 1:2:0:1 high‐Tc cuprates

We present the results of μSR measurements of the transverse field relaxation rate below Tc for seven samples of HgBa2 CuO4+\delta, spanning the underdoped, optimally doped, and nominally overdoped regions of the superconducting phase. On comparison with the “anomalous” thermopower data for these compounds, we find that nominally “overdoped” Hg 1:2:0:1 resembles underdoped compounds in certain respects.
