Preparation and physical properties of (M$_{1-x}$Yb$_{x})$Fe$_{2}$As$_{2}$ (M $=$ Ca, Ba) single crystals

POSTER

Abstract

As judged by $x$-ray diffraction data, single crystals in the series (M$_{1-x}$Yb$_{x})$Fe$_{2}$As$_{2}$ (M $=$ Ca, Ba) with 0 \textless $x$ \textless 0.22 have been made by flux method. Magnetic and electrical properties as well as the specific heat data in the systems (M$_{1-x}$Yb$_{x})$Fe$_{2}$As$_{2}$ (M $=$ Ca, Ba) investigated will be discussed.
