Abstract Negative eigenvalue counting method has been extended to deal with the closed ring with large number of atoms threaded by a magnetic flux. This new method is extremely computer memory-saving and can be used to accurately determine the eigen-values and eigenvectors. As numerical examples, the results of second moment and persistent current are presented.
