Half-metallic materials have attracted much attention in the past decade, particularly in their novel spin polarization properties for potential spintronics applications. Constructing a device-quality film on the nanoscale, however, has become a serious challenge, and this has opened up various opportunities to investigate the underlying growth physics, surface chemistry, and structure-property relations of these materials. In this talk, we will discuss some of our recent work on the growth physics of two important half-metallic nanofilms of CrO2 and Sr2FeMoO6 grown by pulsed laser deposition, and on the prospect of introducing novel magnetic properties into the nanostructures of ZnO and other transparent conductive oxides by appropriate electrochemical doping.
