THE 5-SECOND TRICK FOR FE²�?ZNS CRYSTAL

KLuS 2 single crystal samples undoped and doped with a small (5 %) or superior (38 %) concentration of trivalent thulium or ytterbium ions have been synthesized in the form of slender hexagonal plates. The very low phonon Vitality (�?20 cm ⁻�?) was confirmed working with Raman spectroscopy. Samples ended up examined also by making use of opti
