KFe2Se2 is the parent compound of K-doped iron selenide superconductors.
We elucidate the existing controversies in the newly discovered K-doped iron selenide (K(x)Fe(2-y)Se(2-z)) superconductors. The stoichiometric KFe(2)Se(2) with √2 × √2 charge ordering was identified as the parent compound of K(x)Fe(2-y)Se(2-z) superconductor using scanning tunneling microscopy and spectroscopy. The superconductivity is induced in KFe(2)Se(2) by either Se vacancies or interactin...
متن کاملNanoscale stripe-type phase separation of antiferromagnetic order and superconductivity in K0.75Fe1.75Se2
We report an in-plane optical spectroscopy study on the newly discovered iron-selenide superconductor K0.75Fe1.75Se2. The measurement revealed the development of a sharp reflectance edge at very low frequency below Tc on the relatively incoherent electronic background. The phenomenon was explained as arising from the Josephson-coupling plasmon of superconducting condensate. Together with the tr...
متن کاملNanoscale phase separation of antiferromagnetic order and superconductivity in K0.75Fe1.75Se2
We report an in-plane optical spectroscopy study on the iron-selenide superconductor K0.75Fe1.75Se2. The measurement revealed the development of a sharp reflectance edge below Tc at frequency much smaller than the superconducting energy gap on a relatively incoherent electronic background, a phenomenon which was not seen in any other Fe-based superconductors so far investigated. Furthermore, th...

In this research, Effect of thermal treatment on beneficiation of low-grade laterite nickel by calcination-magnetic separation method was studied. In order to determine the components and elements of the sample, to recognize the main and minor minerals and their bond, and phase transformation caused by thermal treatment, Chemical analysis (XRF and ICP), microscopic studies and XRD analysis ...
متن کاملDextran grafted nickel-doped superparamagnetic iron oxide nanoparticles: Electrochemical synthesis and characterization
In this paper, polymer grafted nickel-doped iron oxide nanoparticles are fabricated via an easy, one-step and fast electrochemical procedure. In the deposition experiments, iron(II) chloride hexahydrate, iron(III) nitrate nonahydrate, nickel chloride hexahydrate, and dextran were used as the bath composition. Dextran grafted nickel-doped iron oxides (DEX/Ni-SPIOs) were synthesized with applying...
