Strain Fields and Critical Phenomena in Manganites II: Spin-Lattice-Energy Hamiltonians
Rohit Singh, Sanjay Puri
The dynamic critical behavior at the paramagnetic-antiferromagnetic (PM-AFM) transition in manganites has recently been studied experimentally [Niermann et al., Phys. Rev. Lett. {\…
Strain Fields and Critical Phenomena in Manganites I: Spin-Lattice Hamiltonians
Rohit Singh, Sanjay Puri
We use a model Hamiltonian to study critical phenomena in manganites. This Hamiltonian includes long-range strain interactions, and a coupling between the magnetic order parameter…
Reply to Comment on Nonlocal quartic interactions and universality classes in perovskite manganites
Rohit Singh, Kishore Dutta, Malay K. Nandy
Comment [arXiv:cond-mat.stat.mech., 1602.02087v1 (2016)] has raised questions claiming that the nonlocal model Hamiltonian presented in [Phys. Rev. E 92, 012123 (2015)] is equivale…
Understanding the metamagnetic transition and magnetic behavior of Ni48Co6Mn26Al20 polycrystalline ribbons
Rohit Singh, Saurabh Kumar Srivastava, Arun K. Nigam +3
In this work we demonstrate that the polycrystalline ribbons of (Ni48Co6)Mn26Al20 with B2 structure at room temperature show a magnetic behavior with competing magnetic exchange in…
Quantum statistical model for superconducting phase in graphene and nanotubes
Shigeji Fujita, Rohit Singh, Salvador Godoy +1
A quantum statistical theory is presented, supporting a superconducting state of an ultrahigh critical temperature (1275 K) in the multiwalled nanotubes reported by Zhao and Beeli…
Scaling Analysis and Application: Phase Diagram of Magnetic Nanorings and Elliptical Nanoparticles
Wen Zhang, Rohit Singh, Noah Bray-Ali +1
The magnetic properties of single-domain nanoparticles with different geometric shapes, crystalline anisotropies and lattice structures are investigated. A recently proposed scalin…
