Evolution of Physical Properties with Mn Content in Sr$_{3}$(Ru$_{1-x}$Mn$_{x})_{2}$O$_{7}$ Single Crystals

ORAL

Abstract

We have systematically studied the doping dependence of physical properties of Sr$_{3}$(Ru$_{1-x}$Mn$_{x})_{2}$O$_{7 }$with 0.0$\le $x$\le $1.0. Although the undoped Sr$_{3}$Ru$_{2}$O$_{7}$ is a paramagnetic metal, partial substitution of Ru by Mn results not only in metal-insulating transition (T$_{MIT})$ but also in complex magnetic ordering at T$_{M}$. Interestingly, the difference between T$_{M}$ and T$_{MIT}$ (T$_{M}<$T$_{MIT})$ increases with increasing doping level x. The correlation between these two transitions will be reported.
