Electrocatalytic Reduction of Oxygen by FePt Alloy Nanoparticles

FexPt100-x nanoparticles of different compositions (x ) 63, 58, 54, 42, 15, and 0) were prepared and loaded onto a glassy carbon (GC) electrode where their catalytic activities in the electroreduction of oxygen were examined and compared. Cyclic and rotating disk voltammetric studies of the resulting FexPt100-x/GC electrodes showed that the catalytic activity for oxygen reduction exhibited a pe...

Highly oriented nonepitaxially grown L10 FePt films

Light–induced magnetization reversal of high-anisotropy TbCo alloy films

Evolution of magnetization reversal mechanism in Fe-Cr alloy films

A large thin film sample of FexCr1−x alloy with a composition gradient x=0.38−0.52 has been prepared by co-sputtering to investigate magnetic anisotropy and magnetization effects on reversal mechanisms. The single-phased Fe-Cr films have a bcc structure with 110 preferred orientation. Since the magnetization decreases as the Fe content is decreased and the uniaxial anisotropy energy keeps at al...
