Orbital order in ZnV $_{2}$ O $_{4}$

Tulika Maitra, Roser Valenti

In view of recent controversy regarding the orbital order in the frustrated spinel ZnV2O4, we analyze the orbital and magnetic groundstate of this system within an ab initio densit…

Effects of Fe substitution on the electronic, transport, and magnetic properties of ZnGa $_{2}$ O $_{4}$ : A systematic ab-initio study

Leonardo Pisani, Tulika Maitra, Roser Valenti

We present a density functional study of Fe doped into the tetrahedral and octahedral cation sites of the wide band gap spinel ZnGa $_{2}$ O $_{4}$ . We calculate the electronic structure…

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 $x = 0.5$ in the bilayer manganites. At $x = 0.5$ , there appears to be a coexistence region of layered A-type antiferromagnetc…

Volume contraction at the Jahn-Teller transition of LaMnO $_{3}$

T. Maitra, P. Thalmeier, T. Chatterji

We have studied the volume collapse of LaMnO $_{3}$ at the Jahn- Teller (JT) transition temperature T $_{J T}$ =750 K which has recently been found in high temperature powder x- ray and…

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 $0.5 < x < 1.0$ have been investigated from a model that incorporates the two $e_{g}$ orbitals at each…
