Abstract An 27Al magic angle spinning (MAS) nuclear magnetic resonance (NMR) study of nominally pure and Cr-doped yttrium-aluminum garnet (Y3Al5O12 and Y3Al5O12:Cr) crystals is reported. It has been shown that the doping by Cr of the Y3Al5O12 crystals leads to the variation of the occupation by Al atoms both octahedrally and tetrahedrally coordinated sites of the garnet lattice.

In order to understand the thermodynamic properties and structural geometry of NH4Al(SO4)2·12H2O, we studied the magic angle spinning nuclear magnetic resonance (MAS NMR) and static NMR as a function of temperature.
