NMR property of rubidium loaded sodalite Original Research Article

27Al NMR property of rubidium-loaded potassium-type sodalite, which has antiferromagnetic transition temperature TN of 80 K, is reported. Similar to the case of potassium-loaded one, monotonous narrow spectrum is seen above TN and broadened one is observed below TN. Separately shifted component, which is seen in the case of sodium-loaded one, is not observed as the potassium-loaded one. When two Gaussian functions are used for fitting, widths of each Gaussian component fairly scale to each other. The ratio between two Gaussian widths takes close value to the case of potassium loading below 65 K and shows difference above 65 K. This difference comes from the raising of TN by replacement of K to Rb.
