Switching-on superparamagnetism in Mn/CdSe quantum dots.
Mn ion doping of CdSe and other semimagnetic quantum dot (QDs) alloys has been an area of active speculation for over a decade. We report evidence of Mn(II) doping of CdSe grown from a cubic single source precursor that is superparamagnetic (SPM) with a blocking temperature of 40 K following thermal annealing. Prior to thermal annealing the 4 nm Mn/CdSe (1% Mn) QDs exhibit mainly paramagnetic b...

Somaiya College of Sc. & Comm 077, India. The nonresonant third order nonlinear optical properties of three different sized Mn-doped ZnSe quantum dots (QDs) are investigated. The nonlinear absorption ...
متن کاملMagnetization in electron- and Mn- doped SrTiO3
Mn-doped SrTiO(3.0), when synthesized free of impurities, is a paramagnetic insulator with interesting dielectric properties. Since delocalized charge carriers are known to promote ferromagnetism in a large number of systems via diverse mechanisms, we have looked for the possibility of any intrinsic, spontaneous magnetization by simultaneous doping of Mn ions and electrons into SrTiO3 via oxyge...
متن کاملMixed valency in polynuclear Mn/Mn, Mn/Mn and Mn/Mn/Mn clusters: a foundation for high-spin molecules and single-molecule magnets
Mixed-valent Mn/O dinuclear and polynuclear molecular compounds containing Mn are almost without exception trapped valence. Large differences between the strengths of the exchange interactions within MnMn, MnMn and MnMn pairs lead to situations where MnMn interactions, the strongest of the three mentioned and antiferromagnetic in nature, dominate the intramolecular spin alignments in trinuclear...
متن کاملSelf-ordered CdSe quantum dots in ZnSe and (Zn,Mn)Se matrices assessed by Transmission Electron Microscopy and Photoluminescence Spectroscopy
Single and multilayer sheets of self-assembled CdSe (QDs) were grown by means of molecular beam epitaxy in both ZnSe and (Zn0.9Mn0.1)Se matrices. Both types of structures were assessed by means of transmission electron microscopy in the scanning, high-resolution, and diffraction-contrast modes. Complementary results from wider sample areas were obtained by means of photoluminescence spectroscop...
