Polar instabilities are well known to be suppressed on scaling materials down to the nanoscale, when the electrostatic energy increase at surfaces exceeds lowering of the bulk polarization energy. Surprisingly, here we report an emergent low symmetry

High-resolution spectroscopic studies of $\mathrm{LaAl}{\mathrm{O}}_{3}$ single crystal doped with holmium ions are reported. Polarized and unpolarized absorption and luminescence spectra were measured in the broad spectral range from 2000 to $23\pha

The work is devoted to a high-resolution spectroscopy study of the perovskite-type single crystals of LaAlO3 doped with non-Kramers rare-earth ions of praseodymium, holmium and thulium. Doublets of a specific shape were observed in the spectra, which
