Sr3Ru2O7 and Sr3Ru1.5Fe0.5O7 have been prepared by the ceramic method. XRD studies show that the phases crystallize as tetragonal unit cells with the space groupI4/mmm. Electric conduction in these phases follows variable range-hopping mechanism but the characteristic energy of hopping in Sr3Ru2O7 is reduced to a great extent. Magnetic susceptibility of Sr3Ru2O7 shows an abrupt rise below 200 K. Sr3Ru1.5Fe0.5O7 is antiferromagnetic.
