概要

• 論文の詳細を見る

• Neutron Rietveld analyses have been carried out on Y_2Ru_2O_7 and Nd_2Ru_2O_7 to clarify the primary mechanism of the transition at T_G to the spin-glass-like state which is accompanied by the specific heat jump. The results indicate that the lattice system does not seem to participate in the transition and changes of the neutron diffraction data with decreasing temperature through T_G can consistently be understood by the ordering of magnetic moments at Ru sites to an almost long range ordered state, even though the low temperature phase is glassy in the macroscopic sense.
