Cu doped ZnO (Zn1− xCuxO, x= 0, 0.02, 0.04 and 0.06) nanopowders have been
synthesized by co-precipitation method and annealed at 500° C for 2h under Ar atmosphere …

Pure ZnO and alkaline metal ion (Mg2+, Ca2+, Sr2+ and Ba2+)-doped ZnO nanoparticles
(NPs) were synthesized by the co-precipitation method. The synthesized nanoparticles …

In order to elucidate room-temperature (RT) ferromagnetism (FM) in ZnO, we have analyzed
a multitude of experimental publications with respect to the ratio of grain-boundary (GB) area …

Undoped and Mn-doped ZnO samples with different percentage of Mn content (1, 2 and
3mol%) were synthesized by a simple solvo-thermal method. We have studied the structural …

A new model is proposed for ferromagnetism associated with defects in the bulk or at the
surface of nanoparticles. The basic idea is that a narrow, structured local density of states N …

Undoped and transition metal (Cu, Co and Mn) doped ZnO nanostructures were
successfully prepared via a microwave-assisted hydrothermal method followed by …

In this work ZnO nanoparticles were synthesized by coprecipitation method. We investigated
the reactivity of 0.24 μm and 50 nm ZnO sample as bulk and nano-sized, respectively …

Dilute magnetic semiconductors such as transition-metal-doped ZnO are potential
candidates for spintronic applications. Transition metals such as Mn, Fe, and Cu when …

Nanograined (grain size 20nm) ZnO films with various Mn content (from 0 to 47at%) were
synthesized by the novel wet chemistry method. The solubility limit for Mn was determined at …

Zn1− xMnxO (x= 0.03, 0.05, 0.07 and 0.10) thin films were synthesized by low cost ultrasonic
spray pyrolysis technique on simple glass substrate at low substrate temperature. The films …
