We have demonstrated that a suitable arrangement of ferromagnetic elliptical nanodots having dimensions less than 100 nm is able to execute logical NAND and NOR operations. This is named as magnetic logic gate (MLG). The NAND and NOR operations are known as universal gate which are able to execute all fundamental logical operations. For a certain range of the external magnetic field, the magnetization of the elliptical dots takes place only along the major axis because of strong uniaxial shape anisotropy. This inherent binary nature of the dots enables them to be used in the MLG. The MLG possesses number of advantages including high integration density, fast operation and non-volatility.
