Structure and Magnetic Properties of Electron Doped YMnO$_{3}$

Combined local and long range structural measurements were conducted on the electron doped ferroelectric Y$_{1-x}$Zr$_{x}$MnO$_{3}$ system. Doping by Zr is found to maintain the hexagonal structure for a large range of x-values. The location of Zr in the lattice is identified and changes in structure with doping are followed. These details of the local structure are examined by x-ray diffraction and x-ray absorption spectroscopy and compared with detailed magnetic studies to correlate the impact of electron doping and atomic structure on the magnetic order in these systems.
