We previously reported that trilayer Nickelate La₄Ni₃O_9.99 exhibits pressure-induced superconductivity above 32.8 GPa. In this study, aiming to enhance the superconducting transition temperature of La₄Ni₃O_10+δ through oxygen content control and element substitution, we synthesized La₄Ni₃O_10.04 and layered cobalt oxide: La₄Co₃O_10+δ. Electrical resistance measurements of these samples under high pressure were also conducted, and the results will be presented.
