Summary

• What is new: Discovery of a new lanthanum superhydride, La$_4$H$_{23}$, with lower stabilization pressure and a higher critical temperature for superconductivity.
• Why this is important: Need for materials that can conduct electricity without resistance at high or room temperature.
• What the research proposes: Using laser heating of LaH$_3$ with ammonia borane at about 120 GPa to create La$_4$H$_{23}$ superhydride.
• Results: La$_4$H$_{23}$ exhibits a maximum critical temperature of 105 K and a critical field of 32 T at 118 GPa, indicating superconductivity and evidence of a pseudogap phase.
