NMR measurements have been made to study the electron correlation effect in metallic layered perovskite compounds Sr+~V~O3,+ i (n = 2, 3 and o~). It has been found that the exchange enhancement of the spin susceptibility increases with decreasing n from o~ to 2 within the random phase approximation.
Single crystals of the title compounds were prepared by solid state reactions from barium carbonate and ruthenium metal using a BaBr 2 flux and investigated by X-ray diffraction method using Mo(Ka) radiation and a Charge Coupled Device (CCD) detector. A structural model for the term n ¼ 2, Ba 5 Ru 2
