Alumni Interaction

We conducted a lecture series where our alumni shared their research

work and experience to engage our research students with various

opportunities.

Getting a closer look on nanoparticles through pair distribution function (PDF)

Center (iNANO) Aarhus University, Denmark, February 26
th
Since the turn of the century, there
has been a clear advancement and
discovery of new functional

materials for advanced
applications like, e.g., energy
technologies and many other

fields. However, highly
disordered materials can be challenging to
characterize, and it is limited to the number of

particles analyzed at a time. This is where the pair
distribution function (PDF) comes in as a handy tool to sort out the difference between a material's bulk
and local structure. The main advantage of PDF is that it never discriminates between Bragg scattering

and diffuse scattering. An essential prospect of the PDF includes crystalline, nanostructured, disordered,
or fully amorphous material.
Magnetic interactions of R and Fe ions in rare-earth ferrite oxide (RFeO3) single

Physics, Shanghai University, China, April 28
th
In the emerging field of spintronic, novel properties
with unprecedented control of magnetism are

prerequisites. Rare-earth ferrite oxide (RFeO3)
materials are outstanding examples for explaining the
temperature and/or magnetic field-induced spin-

reorientation, magnetic reversal, and multiferroic
properties. The discussion started with some basic
information about the perovskite oxides, difficulty, and challenges in

growing a good quality RFeO3 single crystal using Optical Floating Zone (OFZ). At last, Dr. Ramki
