Yttrium aluminium perovskite (YAlO3, aka YAP) are commonly used and studied in lasing applications in thin film and single crystal form typically with the addition of rare earth and transition metal ions. As a substrate, YAP have stabilize many thin films including high temperature superconductors.

With its orthorhombic structure, the various orientations give lots of different options for lattice matches which many other substrates simply can’t, so you often see it being used with rare earths and large lattice parameter films and dopants.
