Magneto-electronics

Uses. Hard ferrites are used widely in electromechanical devices, e.g., generators, relays, motors, and magnetos electronic applications, e.g., loudspeakers, traveling-wave lubes, and telephone ringers and receivers aniitheft tags, holding devices such as door closers, seals, and latches ... 

One such quantum property of the electron is its spin, i.e., its magnetism. Devices that rely on an electron s spin to perform their functions form the foundation of spintronics (short for spin-based electronics), also defined as magneto-electronics. Information-processing teclmology has thus far relied on purely charge-based devices, ranging from the now outdated vacuum tube to today s million-transistor microchips. The conventional electronic... 

However, with the emergence of new exotic materials and their fascinating physical properties it will be possible to manipulate the spins of the electrons. The manipulation of spin analogous to that of the charge would give rise to a new era of magneto-electronics, which with analogy...
