Point contact spectroscopy of Pr${}_{2-x}$Ce${}_x$CuO${}_4$ in high magnetic fields

Sung Hee Yun, Neesha Anderson, Bing Liang +2

We have studied the density of states of the normal state of the electron-doped superconductor Pr${}_{2-x}$Ce${}_x$CuO${}_4$ at low temperatures and in magnetic fields up to 31 Tesla usi…
