摘要：
In order to gain insight into suppression of the ferromagnetic ordering temperature, local studies utilizing Ru-99,Ru-101 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.
