Abstract
The physical properties of Al1−x Cr x K(SO4)2·12H2O (x = 0, 0.07, and 0.2) were studied as a function of temperature using magic angle spinning nuclear magnetic resonance for 27Al. On the basis of the physical properties of pure AlK(SO4)2·12H2O, the effects of partially replacing Al3+ with Cr3+ ions were examined. Molecular motion changed with the concentration of Cr3+ ions. The relaxation process near 320 K was found to undergo molecular motion as described by the Bloembergen–Purcell–Pound theory. The activation energies, phase transition temperatures, and spin–lattice relaxation times in the rotating frame T 1ρ changed with the concentration of paramagnetic ions.
