Pressure induced effects on the Fermi surface of superconducting 2H-NbSe${}_2$

H. Suderow, V. G. Tissen, J. P. Brison +2

The pressure dependence of the critical temperature $T_c$ and upper critical field $H_{c2}(T)$ has been measured up to 19 GPa in the layered superconducting material 2H-NbSe${}_2$. R…
