X-ray Crystallography

X-ray Crystallography

The size of the unit cell and the arrangement of atoms in a crystal may be determined from measurements of the diffraction of X-rays by the crystal, termed X-ray crystallography.
Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

Double Resonance Techniques: Overview

Double Resonance Techniques: Overview

Double resonance techniques in Nuclear Magnetic Resonance (NMR) spectroscopy involve the simultaneous application of two different frequencies or radiofrequency pulses to manipulate and observe two distinct nuclear spins. One important application of double resonance is spin decoupling, which selectively suppresses coupling with one type of nucleus while observing the NMR signal from another nucleus, simplifying the spectrum and enhancing resolution.
Spin decoupling is usually achieved by...

Background:

Cerium (Ce) and praseodymium (Pr) are rare-earth elements exhibiting unique electronic properties under pressure.
Both elements undergo a volume collapse transition driven by similar electronic mechanisms involving 4f electrons.
Despite similar mechanisms, Ce retains its crystal symmetry while Pr transforms to a lower symmetry orthorhombic structure.

Purpose of the Study:

To investigate the influence of strain/compression rate on the volume collapse phase transitions in Ce and Pr.
To explore the kinetic differences between the phase transformations in Ce and Pr under dynamic compression.
To elucidate the role of electronic structure and crystal symmetry in these pressure-induced transitions.

Main Methods:

Dynamic compression experiments utilizing a diamond anvil cell.
Systematic variation of strain/compression rates across four orders of magnitude.
Analysis of volume collapse phase transitions and their kinetic behavior.

Main Results:

Cerium's volume collapse transition could not be overdriven in pressure, indicating a rapid kinetic process.
Fast compression rates in praseodymium shifted the phase boundary to higher pressures, suggesting slower kinetics.
The observed kinetic differences are linked to the distinct outcomes of the volume collapse in Ce and Pr, particularly the change in crystal symmetry for Pr.

Conclusions:

The study highlights significant kinetic disparities in the volume collapse phase transitions of cerium and praseodymium.
Dynamic compression experiments reveal that praseodymium's phase transformation kinetics are considerably slower than cerium's.
These findings underscore the interplay between electronic structure, crystal symmetry, and the kinetics of pressure-induced phase transitions in rare-earth elements.
