Experimental and theoretical demonstration of negative magnetization induced by particle size reduction in nano-form GdCaMnO
Papri Dasgupta, Sanjukta Paul, S. Kumar +2
We report a pervasive phenomenon of gradual emergence of negative magnetization in typical MnO orthorhombic perovskite manganites in nano form (with being…
Mixed-order transition and tricritical point associated with checkerboard supersolidity in the two-dimensional model
Amrita Ghosh, Satyaki Kar, Sudhakar Yarlagadda
We use Quantum Monte Carlo method employing stochastic-series-expansion technique to study the ground state properties of the model on a square lattice. We find that, awa…
Study of the ferromagnetic-insulator phase in manganites
Sanjukta Paul, Sudhakar Yarlagadda
Understanding the coexistence of ferromagnetism and insulating behavior in manganites is an unsolved problem. We propose a localized-band model involving effective intermediate-ran…
Study of supersolidity in the two-dimensional Hubbard-Holstein model
A. Ghosh, S. Kar, S. Yarlagadda
We derive an effective Hamiltonian for the two-dimensional Hubbard-Holstein model in the regimes of strong electron-electron and strong electron-phonon interactions by using a nonp…
Giant magnetoelectric effect in pure manganite-manganite heterostructures
Sanjukta Paul, Ravindra Pankaj, Sudhakar Yarlagadda +2
Obtaining strong magnetoelectric couplings in bulk materials and heterostructures is an ongoing challenge. We demonstrate that manganite heterostructures of the form ${\rm (Insulat…
Correlation between battery material performance and cooperative electron-phonon interaction in LiCoMnO
Krishna Rao Ragavendran, Prabhat Mandal, Sudhakar Yarlagadda
Understanding the basic physics related to archetypal lithium battery material (such as LiCoMnO) is of considerable interest and is expected to aid designing of c…
