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…

Charge and orbital order due to cooperative Jahn-Teller effect in manganite chains
Ravindra Pankaj, Sudhakar Yarlagadda
We derive an effective Hamiltonian that takes into account the quantum nature of phonons and models cooperative Jahn-Teller effect in the adiabatic regime and at strong electron-ph…
