Superconducting Lanthanum Nickel Oxides with Bilayered and Trilayered Crystal Structures

Hiroya Sakurai, Yoshihiko Takano

In 2023, superconductivity in La $_{3}$ Ni $_{2}$ O $_{7}$ was discovered under high pressures above approximately 14 GPa. In addition to its high transition temperature ($T_{\mathrm{c}} \sim…

High-pressure synthesis of bilayer nickelate Sr $_{3}$ Ni $_{2}$ O $_{5}$ Cl $_{2}$ with tetragonal crystal structure

Kazuki Yamane, Yoshitaka Matsushita, Shintaro Adachi +5

A novel oxychloride, Sr $_{3}$ Ni $_{2}$ O $_{5}$ Cl $_{2}$ , was synthesized for the first time under high pressure of 10 GPa at 1400 $^{\circ}$ C, motivated by a theoretical prediction of…

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…
