  • Recently, we have seen a rapid advance in the evolving field of spin electronics (or spintronics). In spintronics, some feasibilities of new electronic applications utilizing spin degree of freedom have been explored. Diluted magnetic semiconductors (DMSs) are premising materials for spintronics because they have both charge and spin degree of freedom in a single substance. DMSs are refereed to semiconductor alloys in which some atoms are randomly substituted for by magnetic atoms. (omitted)

  • Many devices based on magnetism such as power generators and motors are frequently used in real life. Magnetic materials at nano-scale can be utilized as storage devices such as magnetic tapes and hard disk drives as well as spintronics. In addition to spintronics, magnetic biosensors are another interesting application of magnetic devices at nano-scale. Here, we briefly review magnetic nano-biosensors including Hall-effect sensors, giant magnetoresistive sensors, and tunnel magnetoresistive sensors for many biomedical applications.
