The detailed study of magnetic properties, including dc and ac measurements, has been carried out on the Bi-Cr-Sb-O pyrochlore. The region of pyrochlore phase existence was determined and photocatalytic properties have been also studied. We revealed that the Bi-Cr-Sb-O pyrochlore phase occurs al...detailed
The Gibbs energy of formation of Tm2Ru2O7(s) has been determined employing a solid-state electrochemical cell incorporating an oxide ion conducting electrolyte. The reversible electromotive force (e.m.f.) of the following cell was measured:Cell : (−)Pt/{Tm2O3(s) + Tm2Ru2O7(s) + Ru(s)}//CSZ//O2(p...detailed
In this work, pyrochlore glass-ceramics (GCs)for uranium immobilization were synthesized by a pretreatment and melting-heat treatment method. The effects of different uranium contents on the phase composition, microstructure, uranium valence and chemical durability of the glass-ceramics were sys...detailed
We study the ferromagnetic criticality of the pyrochlore magnet Lu2V2O7 at the ferromagnetic transition TC≈70K from the isotherms of magnetization M(H) via an iteration process and the Kouv7el-Fisher method. The critical exponents associated with the transition are determined 7β= 0.32(1), γ= ...detailed
