Research interests

· Magnetic properties of metals, alloys and intermetallic compounds, magnetoelastic phenomena, magnetic and structural phase transitions.

· Methods of synthesis of intermetallic compounds.

Main directions of the research activity

· Study of the magnetic, transport and magnetoelastic properties of RCo₃ intermetallic compounds.

Main accomplishments

- Finding and experimental investigation of the phenomenon of temperature-induced itinerant-electron metamagnetism in intermetallic compounds of the RCo₃ series (Fig. 8).

Fig. 8. Temperature dependence of the electrical resistivity of the Ho1‑xYxCo3 compounds. The temperature-induced metamagnetic transition is smeared at high temperatures (see the curve for HoCo3) and becomes sharper when occurring at lower temperature (curve for Ho0.6Y0.4Co3) [I.S. Dubenko, I.Yu. Gaidukova, E. Gratz, K. Inoue, A.S. Markosyan, V.E. Rodimin, Physica B 319 (2002) 21-27)].
