Investigation of the Phase
Diagram of Selected Materials using μSR and μSR under Pressure.
Aim of the project (project
summary and referee report).:
The aim of this work is to
the magnetic properties of selected compounds using, among
traditional techniques, µSR and
µSR under pressure. In a µSR experiment, a 100 %
polarized muon (spin 1/2 elementary particles) beam is
implanted into the investigated sample where they stop in
interstitial crystallographic positions and their spin
performs Larmor precession around the local field at the place
where they come at rest. Muons disintegrate with a lifetime of
2.2 µs, emitting a positron preferentially along the
muon spin at the moment of disintegration. By registering,
with detectors placed around the sample, the spatial
distribution of the emitted positrons, one can obtain valuable
information about the value of the local field, field
distribution and field dynamics.
The proposed research topics are of high interest
in both fundamental (investigate the peculiarities of the
phase diagram of the selected compounds and correlate them
with the theoretical predictions) and applied physics. As
said, the methods will be the combination μSR-pressure,
together with classical macroscopic methods and X-Ray
diffraction. Below, the list of principal expected results of
this project is presented.
