Notes:
Electron paramagnetic resonance (EPR) studies performed at room tempertaure in Mn2+ doped Cs2NaYCl6 single crystals (elpasolite) showed that the Mn2+ ion occupies a tetragonal symmetry site in the cubic crystalline lattice. In contrast with previous results on elpasolite, where trivalent rare earth impurities occupy Oh sites, and divalent europium impurities occupy trigonal sites, this work reports, the first evidence of an impurity in a tetragonal symmetry site in this host with principal axes along 〈100〉 crystallographic directions. The unusually large total splitting of the EPR spectrum (∼10 000×10−4 cm−1) is discussed in order to establish a tentative model for the site.
