Magnetic field as a probe of gap energy scales in YBCO
Abstract
Among high Tc materials, the YBCO (YBa2Cu3O7-x) compounds are special since they have superconducting chains as well as planes. We show that a discontinuity in the density of states as a function of magnetic field may appear at a new energy scale, characteristic of the chain and distinct from that set by the d wave gap. This is observable in experimental studies of the thermodynamical properties of these systems, such as the specific heat.
