Synthesis and room-temperature ferromagnetic properties of single-crystalline Co-doped SnO2 nanocrystals via a high magnetic field

Studies of dense electronic excitation induced modification in cobalt doped SnO2 thin films prepared by RF sputtering technique

“…But further increase in fluence to 1 Â 10 13 ions/cm 2 , it's ferromagnetic behavior exceeds from the pristine sample. This sudden increase in ferromagnetic behavior in Cobalt doped SnO 2 is attributed to the oxygen vacancy, formation of secondary phases [37] as observed from XRD results. Furthermore, the transition occurs after fluence of 5 Â 10 12 ions/cm 2 where coercivity is maximum due to vacancy induced magnetism [38] (of about 140 Oe) with a symmetric hysteresis loop and saturation magnetization of about 2.1 Â 10 À3 emu/ cm 3 .…”

Magnetic field-assisted solvothermal assembly of one-dimensional nanostructures of Ni–Co alloy nanoparticles

“…With the development of preparation methods, magnetic field, similar to the conventional reaction conditions such as temperature and pressure, has been introduced as a new parameter to the synthesis system for the reaction control in electrochemical process [6,7], solid state reactions [8,9], and chemical vapor deposition [10]. Recently, magnetic field-assisted hydrothermal processing has been the subject of fruitful research [11][12][13][14][15][16].…”

Preparation and near-infrared absorption of nano-SnO2/SiO2 assemblies with doping and without doping

“…But the studies on the near-infrared absorption of Sb-and Pd-doped assemblies are very rare. As we know, the electrical, optical and magnetic properties of nanomaterials can be modified by doping [13,[14][15][16][17][18][19]. For example, to modulate the optical properties, different rare earth elements were used as dopant in materials [20][21][22][23].…”
