Characteristic Energy of the Coulomb Interactions and the Pileup of States

Daniel Mazur, K. E. Gray, J. F. Zasadzinski +4

Tunneling data on $\mathrm{L}{\mathrm{a}}_{1.28}\mathrm{S}{\mathrm{r}}_{1.72}\mathrm{M}{\mathrm{n}}_2{\mathrm{O}}_7$ crystals confirm Coulomb interaction effects through the $\sqrt{\mathrm{E}}$ dependence of the density of states. Importantly…
