Room Temperature Ferromagnetism of Ni-doped SnO2 System
A series of Sn1-xNixO2 films were fabricated by sol-gel method. All samples have pure rutile structure and exhibit room temperature ferromagnetism (RTFM). Magnetic moment per Ni ion decreases with the increase of Ni doping because antiferromagnetic super-exchange interaction takes place in the nearest neighbour Ni ions for the samples with high x. The results of the annealing at oxidizing and r...
متن کاملRoom Temperature Ferromagnetism in Cobalt Doped ZnO Nanoparticles
In this work we report synthesis and magnetic characterization of cobalt doped ZnO nanoparticles (with different percent of doped cobalt oxide). Synthesis of the materials was carried out at room temperature by polyacrylamide-gel method, using zink sulfate and cobalt nitrate as source materials, acrylamide as monomer and N,N-methylene bisacrylamide as a lattice reagent. Characterization of the ...

متن کاملRoom-temperature ferromagnetism of graphene.
Aiming at molecular-based magnets, ferromagnetism of pure carbon-based materials is fundamentally and technologically extremely important for many applications. While it is still not fully understood, many recent theoretical works have suggested that one-atom-thick two-dimensional graphene materials may show ferromagnetism due to the existence of various defects or topological structures as the...
متن کاملControlled synthesis and characterization of hollow flower-like silver nanostructures
BACKGROUND The synthesis of anisotropic silver nanoparticles is a time-consuming process and involves the use of expensive toxic chemicals and specialized laboratory equipment. The presence of toxic chemicals in the prepared anisotropic silver nanostructures hindered their medical application. The authors have developed a fast and inexpensive method for the synthesis of three-dimensional hollow...
