Spinel ferrite nanocrystals embedded inside ZnO: magnetic, electronic and magneto-transport properties

Shengqiang Zhou, K. Potzger, Qingyu Xu +8

In this paper we show that spinel ferrite nanocrystals (NiFe2O4, and CoFe2O4) can be texturally embedded inside a ZnO matrix by ion implantation and post-annealing. The two kinds o…

Ferromagnetism and suppression of metallic clusters in Fe implanted ZnO - a phenomenon related to defects?

Shengqiang Zhou, K. Potzger, G. Talut +7

We investigated ZnO(0001) single crystals annealed in high vacuum with respect to their magnetic properties and cluster formation tendency after implant-doping with Fe. While metal…

Suppression of secondary phase formation in Fe implanted ZnO single crystals

K. Potzger, Shengqiang Zhou, H. Reuther +5

Unwanted secondary phases are one of the major problems in diluted magnetic semiconductor creation. Here, the authors show possibilities to avoid such phases in Fe implanted and po…

Absence of ferromagnetism in V-implanted ZnO single crystals

Shengqiang Zhou, K. Potzger, H. Reuther +4

The structural and magnetic properties of V doped ZnO are presented. V ions were introduced into hydrothermal ZnO single crystals by ion implantation with fluences of 1.2*10^16 to…

Electronic structure study by means of X-ray spectroscopy and theoretical calculations of the "ferric star" single molecule magnet

A. F. Takacs, M. Neumann, A. V. Postnikov +5

The electronic structure of the single molecule magnet system M[Fe(L)2]3*4CHCl3 (M=Fe,Cr; L=CH3N(CH2CH2O)2) has been studied using X-ray photoelectron spectroscopy, X-ray absorptio…
