Theory of magnetism in LaNiMnO
Prabuddha Sanyal
The magnetism of ordered and disordered LaNiMnO is explained using a model involving double exchange and superexchange. The concept of majority spin hybridization in the la…
Understanding ferromagnetism in Cr-based 3d-5d double perovskites
Prabuddha Sanyal
Ferromagnetism in Cr-based double perovskites is analyzed using effective model as well as simulation approach. Starting from a microscopic model proposed recently for this class o…
Novel effects of localization due to `intrinsic disorder' in the `two-fluid' model for manganites
Prabuddha Sanyal, V. B. Shenoy, H. R. Krishnamurthy +1
We discuss the effects of a novel polaronic disorder in the recently proposed two-fluid model for manganites. Using effective field theory as well as direct numerical simulations,…
A Magnetic Model for the Ordered Double Perovskites
Prabuddha Sanyal, Pinaki Majumdar
We construct an effective spin model from the coupled spin-fermion problem appropriate to double perovskites of the form A_2BB'O_6. The magnetic model that emerges is reminiscent o…
Unusual doping and temperature dependence of photoemission spectra from manganites
Prabuddha Sanyal, Subhra Sen Gupta, Nandan Pakhira +3
A recent, major, puzzle in the core-level photoemission spectra of doped manganites is the observation of a 1-2 eV wide shoulder with intensity varying with temperature T as the sq…
