Study of the ferromagnetic activation in ZnO diluted magnetic semiconductors


EMSL Project ID
16694

Abstract

We wish to study the in situ activation of ferromagnetic ordering in Mn2+:ZnO using vibrating sample magnetometry. We have previously shown that decomposition of amines activated ferromagnetism, but we would gain a greater understanding of the physical processes by measuring the magnetic properties of the material as a function of temperature.
