Abstract
The effect of dilution on the critical property of a magnet is studied by the renormalization group technique. It is found in the limit of weak dilution and the weak exchange coupling that the critical exponent may change by the existence of correlation in random occupation of sites. In the bond-random problem the critical property will depend on the randomness imposed on the system.Keywords
