Phase diagram of pressure-induced high temperature superconductor La $_{3}$ Ni $_{2}$ O $_{7 + δ}$

Yuta Ueki, Hiroya Sakurai, Hibiki Nagata +7

We successfully synthesized samples of La $_{3}$ Ni $_{2}$ O $_{7 + δ}$ ( $δ = - 0.50$ , $- 0.16$ , $0.00$ , $+ 0.01$ , and $+ 0.12$ ) and measured the resistance under extremely high pressures usin…

Pressure-induced superconductivity in La $_{4}$ Ni $_{3}$ O $_{10 + δ}$ ( $δ$ = 0.04 and -0.01)

Hibiki Nagata, Hiroya Sakurai, Yuta Ueki +7

The superconducting transition temperatures, $T_{c}$ , of La $_{4}$ Ni $_{3}$ O $_{10 + δ}$ ( $δ$ = 0.04 and -0.01) were determined under various pressures up to 124.9 GPa by electr…
