GdI_2: A New Ferromagnetic Excitonic Solid?
A. Taraphder, M. S. Laad, L. Craco +1
The two-dimensional, colossal magnetoresistive system GdI_2 develops an unusual metallic state below its ferromagnetic transition and becomes insulating at low temperatures. It is…
Pairing in disordered s-wave superconductors and the effect of their coupling
Budhaditya Chatterjee, A. Taraphder
Inhomogeneity is introduced through random local interactions (Ui) in an attractive Hubbard model on a square lattice and studied using mean-field Bogoliubov-de Gennes formalism. S…
A study of long range order in certain two-dimensional frustrated lattices
Uma Bhaumik, A. Taraphder
We have studied the Heisenberg antiferromagnets on two-dimensional frustrated lattices, triangular and kagome lattices using linear spin-wave theory. A collinear ground state order…
Magnetic properties of doped GdI2
T. Maitra, A. Taraphder, A. N. Yaresko +1
Motivated by the recent experimental studies on layered ferromagnetic metallic system GdI2 and its doped variant GdI2Hx we develop a model to understand their ground state magnetic…
Charge order and phase segregation in overdoped bilayer manganites
T. Maitra, A. Taraphder, H. Beck
There have been recent reports of charge ordering around in the bilayer manganites. At , there appears to be a coexistence region of layered A-type antiferromagnetc…
Orbital ordering and magnetic structures in $\LMFO$ and $\LWFO$ double perovskites
A. Taraphder, F. Guinea
We analyzed the possible magnetic and orbital orderings of double perovskites, using a simple extension of the double exchange model well suited for these compounds. Orbital orderi…
