Electronic structure and magnetic properties of 3d-4f double perovskite material
S. Kundu, A. Pal, Amit Chauhan +9
Double perovskite-based magnets wherein frustration and competition between emergent degrees of freedom are at play can lead to novel electronic and magnetic phenomena. Herein, we…
Critical behavior and magnetic relaxation dynamics of Nd0.4Sr0.6MnO3 nanoparticles
S. Kundu, T. K. Nath
Detailed dc and ac magnetic properties of chemically synthesized Nd0.4Sr0.6MnO3 with different particle size (down to 27 nm) have been studied in details. We have found ferromagnet…
An Automated Ac Susceptibility Set up Fabricated Using a Closed-Cycle Helium Refrigerator
S. Kundu, T. K. Nath
We have described here the design and operation of an automated ac susceptibility set up using a closed cycle helium refrigerator. This set up is useful for measuring linear and no…
