Myakush O. Phase equilibria, crystal structures and physical properties of compounds in system Y-{Ru,Rh,Pd}-Ga and {Ce,Ho}-Ru-Ga.

Thesis is contain the results of the investigation of the components in the ternary systems Y-{Ru,Rh,Pd}-Ga and {Ce,Ho}-Ru-Ga. Phase equilibria have been established in the ternary systems Y-{Ru,Pd}-Ga and {Ce,Ho}-Ru-Ga at whole concentration rang e and Y-Rh-Ga (0-0,50 at.p. Rh) at 870K. 42 new ternary gallides are observed in the investigation systems and 66 compounds have been found in the systems R-{Ru,Rh,Pd,Ir,Pt,Ag,Au}-Ga. The crystal structure of 1 binary and 90 ternary compounds have been d etermined by X-ray diffraction methods. The magnetic properties of the R3MxGa11-x compounds have been studied over the temperature range 5-550K. The temperature dependence of the resistivity of 11 ternary gallides have been investigated over the temperat ure range 77-367K.
