Effects of the pseudo-gap on the field-induced kinetic energy density of Bi${}_2$Sr${}_2$CaCu${}_2$O${}_{8+\delta }$ single crystals

We report on magnetization experiments from which we obtain the field-induced kinetic energy density, $E_k$, in the superconducting phase of several Bi${}_2$Sr${}_2$CaCu${}_2$O${}_{8+\delta }$ s…
