Spintronics
Exploiting the electron spin in electronics is the central aim of spintronics. Thus, understanding spin transport poses one of the major challenges in this field. Our interests in this field have focused on GaMnAs which is a promising material for spintronics applications, transport properties near ferromagnetic phase transitions, as well as the anomalous Hall effect.
