摘要：
Recent Nernst and interlayer transport experiments in Bi2Sr2CaCu2O8+y (BSCCO) high temperature superconductors report hugely different limiting magnetic flelds. We demonstrate that both fields convert to the same pseudogap energy scale T* upon transformation as orbital and Zeeman critical fields, respectively. We suggest a consistent interpretation of this finding based on separation of spin and charge degrees of freedom residing in different regions of a truncated Fermi surface.
