Evolution of superconductivity and magnetism in La$_{1-x}$Yb$_{x}$Ru$_{2}$P$_{2}$.

ORAL

Abstract

LaRu$_{2}$P$_{2}$, with a 4.1 K transition, is the first known pnictide-based superconductor. Sharing structural and electronic elements similar to those of the unconventional Fe-pnictide superconductors, it is of interest to investigate the parameter space in which a superconducting ground state survives. We present preliminary indications of more interesting magnetic behavior and structural tuning behavior when paramagnetic Yb is substituted for La in La$_{1-x}$Yb$_{x}$Ru$_{2}$P$_{2}$, and investigate potential heavy fermion behavior in the Yb end-member of this series.
