Superconducting and magnetic phase diagram of RbEuFe4As4 and CsEuFe4As4 at high pressure
Daniel E. Jackson, Derrick VanGennep, Wenli Bi +7
The recently discovered (Rb,Cs)EuFe4As4 compounds exhibit an unusual combination of superconductivity (Tc = 35 K) and ferromagnetism (Tm = 15 K). We have performed a series of x-ra…
Superconductivity of barium-VI synthesized via compression at low temperatures
D. E. Jackson, D. VanGennep, Y. K. Vohra +2
Using a membrane-driven diamond anvil cell and both ac magnetic susceptibility and electrical resistivity measurements, we have characterized the superconducting phase diagram of e…
Evolution of the Fermi surface of BiTeCl with pressure
D. VanGennep, D. E. Jackson, D. Graf +2
We report measurements of Shubnikov-de Haas oscillations in the giant Rashba semiconductor BiTeCl under applied pressures up to ~2.5 GPa. We observe two distinct oscillation freque…
Pressure-induced superconductivity in the giant Rashba system BiTeI
D. VanGennep, A. Linscheid, D. E. Jackson +7
At ambient pressure, BiTeI is the first material found to exhibit a giant Rashba splitting of the bulk electronic bands. At low pressures, BiTeI undergoes a transition from trivial…
