Neutron scattering study of high-pressure phases obtained by thermobaric treatment

A technique of thermobaric quenching has been developed at the Institute of Solid Slate Physics RAS, which made it possible to prepare and study bulk samples of high-pressure phases in a metastable state at ambient pressure. The paper briefly discusses results of recent neutron scattering investigat ions of the crystal structure and lattice dynamics of high-pressure phases and forms of various alloys and compounds, such as the bulk amorphous alloy s Ga-Sb, GaSb-Ge, Zn-Sb, Al-Ge, amorphous ice and metal hydrides TiH, Mn-H, PdH and NiH.
