Systematic growth and physical properties of BaFe$_{2-x-y}$Cr$_{y}$Ni$_{x}$As$_{2}$
ORAL
Abstract
We have successfully grown the single crystals of BaFe$_{2-x-y}$Cr$_{y}$Ni$_{x}$As$_{2}$ with a series of Ni and Cr doping levels. Their physical properties were studied by the elastic neutron scattering and transport measurements. It is found that Cr doping is a very efficient way of suppressing the superconductivity in the BaFe$_{2-x}$Ni$_{x}$As$_{2}$ system with little change of the T$_{S}$ and T$_{N}$. The magnetic and electronic properties without the presence of the superconductivity may be thus investigated at low temperature.
