Synthesis of high-Curie-temperature Fe0.02Ge0.98 quantum dots.
Self-assembled Fe(0.02)Ge(0.98) dilute magnetic quantum dots show a high Curie temperature above 400 K. Such extraordinary magnetic properties can potentially resolve the critical problem of power dissipation in today's integrated circuits and lead to the realization of a new class of spintronics devices.
