Structure and magnetic properties of Mn-doped ZnO semiconductors

Structural and magnetic properties of Mn-doped ZnO powders

“…The magnetic behavior of Mn-doped ZnO (ZnO:Mn) has been studied extensively, and different magnetic behaviors, like spin glass [6], paramagnetism [7,8], antiferromagnetism [6], and ferromagnetism (FM) have been all reported [9][10][11][12]. These results show that the magnetization of ZnO:Mn is strongly dependent on the preparation method and procedure, and seems to be sensitive to the crystalline structure and the concentration of oxygen vacancies and defects.…”

Improvement of optical properties of nanocrystalline Fe-doped ZnO powders through precipitation method from citrate-modified zinc nitrate solution

“…Interestingly, there are two general routes to diminish a particle size of ZnO by a precipitation method. Firstly, the use of surfactant to modify the zinc precursor solution such as polyethylene glycol [1], diethanolamine (DEA) [2], triethanolamine (TEA) and cetyltrimethylammonium bromide (CTAB) [3] and secondly, the use of transition metal ions to substitute at Zn sites in the ZnO structure such as Al [4], Co [5], Mn [6] and Fe [7]. Nowadays, the preparation of nanocrystalline Fe-doped ZnO powders has been interesting because of its multifunctional material.…”

Magnetic properties of Co-doped ZnO prepared by sol–gel method

“…Because we have got the definite regularity of magnetism dependent Co content, the upper limit of doping content is not discussed. The detailed preparation process and reaction mechanism were described in our previous report [18]. It is worth declaring that the sintering process was carried out in air.…”
