B. Ghosh,Sekhar C. Ray,Mbule Pontsho,Sweety Sarma,Dilip Kumar Mishra,Y. F. Wang,W. F. Pong,André M. Strydom +7 more
TL;DR: In this article, a comparative study has been made for the defect induced room temperature ferromagnetism of single crystal, poly-crystal, and nanorod zinc oxide (ZnO) based on the magnetic properties and electronic properties by means of X-ray absorption near edge structure spectroscopy (XANES), X -ray photoelectron spectroglobalization, ultraviolet photo electrophoresis (UPS), valence band photoemission spectromission (VB-PES), and SQUID-type magnetometry.
