Local Studies of the Ferromagnetic Ordering Temperature Suppression in SrRuO3
Abstract
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.
