NONCONTACT WRITING OF NANOMETER SCALE MAGNETIC BITS USING HEAT FLOW INDUCED SPIN TORQUE EFFECT

摘要

A mechanism is provided for noncontact writing. Multiple magnetic islands are provided on a nonmagnetic layer. A reference layer is provided under the nonmagnetic layer. A spin-current is caused to write a state to a magnetic island of the multiple magnetic islands by moving a heat source to heat the magnetic island.
