Doping Dependence of Structural, Electrical and Magnetic Properties of Sr$_{3}$(Ru$_{1-x}$Mn$_{x})_{2}$O$_{7}$ Single Crystals

We have studied the doping dependence of structural, electrical and magnetic properties of Sr$_{3}$(Ru$_{1-x}$Mn$_{x})_{2}$O$_{7}$ with 0.0$\le $x$\le $1.0. Our single crystal X-ray diffraction refinements show that the RuO6 octahedron rotates about 7$^{o}$ in undoped Sr$_{3}$Ru$_{2}$O$_{7}$. With the partial substitution of Ru by Mn, the rotation is gradually attenuated. Correspondingly, the electrical and magnetic properties of Sr$_{3}$(Ru$_{1-x}$Mn$_{x})_{2}$O$_{7}$ vary with x. We will discuss the correlation between structure and physical properties in this system.
