The authors report the synthesis of (La0.9Y0.1)H10 superhydrides and their characterization using synchrotron-based, spatially resolved x-ray diffraction and electrical transport imaging. They reveal μm-scale structural inhomogeneity with coexisting cubic and hexagonal clathrate phases exhibiting distinct superconducting transition temperatures.
