The main fields of study
Study of pressure effect on the magnetic properties of
metals, alloys and intermetallic compounds.
Study of magnetic properties and the effects of pressure in the iron-based superconductors.
Some main results
Detailed investigations of magneto-volume effects in transition metals
and their alloys in order to reveal main mechanisms of electronic
structure modification under pressure.
Study of pressure effects in magnetic susceptibility of intermediate
valence systems, based upon rare-earth elements Ce, Sm, Yb.
Investigation of magnetic state in magnetically ordered oxides
of Mn, Co and Ru.
Study of anomalous behavior of magnetic susceptibility for High Tc
compounds FeSe(Te) in the normal state under pressure.
Experimental equipment allows to study:
The temperature dependence of the magnetic susceptibility
in the range 4.2 - 350 K in magnetic field up to 1 T by a Faraday method
with a sensitivity of about 10-9
A range of the measured values of susceptibility is about
emu and the accuracy is not worse then 0.5 %.
The effect of helium gas pressure up to 2 kbar on the magnetic
susceptibility in the temperature range 20,3-300 K by a levitation method
based on the principle of a free suspension of the sample in strong and
non-uniform magnetic field. The relative errors are about 0,03 %.
Another device for the pressure effect study is a pendulum
type magnetometer placed directly into the pressure cell, which has the
similar technical characteristics.
