Local studies of the ferromagnetic ordering temperature suppression in   SrRuO3
  In order to gain insight into suppression of the ferromagnetic ordering temperature, local studies utilizing 99,101Ru zero-field spin-echo NMR, along with complimentary magnetization, high-angle x-ray diffraction, and Ru K-edge XAFS measurements, have been carried out on samples of SrRuO3 annealed at both "ambient" (atmospheric) pressure and "high-pressure" oxygen (600 atm). For the "high pressure" sample, the results indicate structural disorder and the existence of some vacancies on the Ru sites, along with a reduced magnetic ordering temperature.
