Abstract

NMR spin shift data of La1:85Sr0:15CuO4, HgBa2CuO4+6 at ambient pressure, and of YBa 2Cu4O8 at pressure up to 63 kbar are discussed that fail the traditional single-electronic fluid picture used for the discussion of NMR data. Instead the results point to a common explanation for all three systems in terms of two electronic components. One of them has a temperature-dependent magnetic susceptibility while the second component, as well as its coupling to the first component, are constant above the superconducting transition temperature Tc. All susceptibilities vanish below Tc.
