Coherent Spin-Phonon Coupling in the Layered Ferrimagnet Mn3Si2Te6
L. M. Martinez, Y. Liu, C. Petrovic +9
We utilize ultrafast photoexcitation to drive coherent lattice oscillations in the layered ferrimagnetic crystal Mn3Si2Te6, which significantly stiffen below the magnetic ordering…
Study of the Berezinskii-Kosterlitz-Thouless transition: An unsupervised machine learning approach
Sumit Haldar, Sk Saniur Rahaman, Manoranjan Kumar
The Berezinskii-Kosterlitz-Thouless (BKT) transition in magnetic system is an intriguing phenomena and an accurate estimation of the BKT transition temperature has been a long-stan…
Machine learning approach to study quantum phases of a frustrated one dimensional spin-1/2 system
Sk Saniur Rahaman, Sumit Haldar, Manoranjan Kumar
Frustration driven quantum fluctuation leads to many exotic phases in the ground state and study of these quantum phase transitions is one of the most challenging areas of research…
Study of magnetization relaxation in molecular spin clusters using an innovative kinetic Monte Carlo method
Sumit Haldar, S. Ramasesha
Modeling blocking temperature in molecular magnets has been a long standing problem in the field of molecular magnetism. We investigate this problem using a kinetic Monte Carlo (kM…
Magnetocaloric effect in molecular spin clusters and their assemblies: model exact and Monte Carlo studies
Sumit Haldar, S. Ramasesha
We study the magnetocaloric effect (MCE) in spin clusters of six spins with site spins , and for different exchange anisotropies. We also study MCE in an assembly of…
Modeling Molecular Magnets with Large Exchange and On-Site Anisotropies
Sumit Haldar, Rajamani Raghunathan, Jean-Pascal Sutter +1
Spins in molecular magnets can experience both anisotropic exchange interactions and on-site magnetic anisotropy. In this paper we study the effect of exchange anisotropy on the mo…
Modeling Magnetic Anisotropy of Single Chain Magnets in Regime
Sumit Haldar, Rajamani Raghunathan, Jean-Pascal Sutter +1
Single molecule magnets (SMMs) with single-ion anisotropies , comparable to exchange interactions J, between spins have recently been synthesized. In this paper, we prov…
