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…
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…
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…
Magnetic and orbital order in overdoped bilayer manganites
Tulika Maitra, A. Taraphder
The magnetic and orbital orders for the bilayer manganites in the doping region have been investigated from a model that incorporates the two orbitals at each…
Magnetic, orbital and charge ordering in the electron-doped manganites
Tulika Maitra, A. Taraphder
The three dimensional perovskite manganites in the range of hole-doping are studied in detail using a double exchange model with degenerate orbitals including intra…
