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

arXiv:2405.19880 · doi:10.7566/JPSJ.93.095003

Abstract

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 electrical resistance measurements with a diamond anvil cell. $T_{c}$ exhibits a strong dependence on oxygen content within the pressure range of approximately 20 GPa and 80 GPa. At 48.0 GPa, $T_{c}$ of La $_{4}$ Ni $_{3}$ O $_{10.04}$ peaks at 36 K, marking the highest $T_{c}$ reported thus far.
