Lifetimes of Magnons in Two-Dimensional Diluted Ferromagnetic Systems
Akash Chakraborty, Paul Wenk, John Schliemann
Spin dynamics in low dimensional magnetic systems has been of fundamental importance for a long time and has currently received an impetus owing to the emerging field of nanoelectr…
Reconsidering the possibility of room temperature ferromagnetism in Mn doped Zirconium oxide
Akash Chakraborty, Georges Bouzerar
The possibility to induce long range ferromagnetic order by doping oxides with transition metal ions has become a very exciting challenge in the last decade. Theoretically, it has…
Spin-wave excitations in presence of nanoclusters of magnetic impurities
Akash Chakraborty, Paul Wenk, Stefan Kettemann +2
Nanoscale inhomogeneities and impurity clustering are often found to drastically affect the magnetic and transport properties in disordered/diluted systems, giving rise to rich and…
Spontaneous magnetization in presence of nanoscale inhomogeneities in diluted magnetic systems
Akash Chakraborty, Paul Wenk, Richard Bouzerar +1
The presence of nanoscale inhomogeneities has been experimentally evidenced in several diluted magnetic systems, which in turn often leads to interesting physical phenomena. Howeve…
Nanoscale inhomogeneities: A new path toward high Curie temperature ferromagnetism in diluted materials
Akash Chakraborty, Richard Bouzerar, Stefan Kettemann +1
Room temperature ferromagnetism has been one of the most sought after topics in today's emerging field of spintronics. It is strongly believed that defect- and inhomogeneity- free…
Magnetic spin excitations in Mn doped GaAs : A model study
Akash Chakraborty, Richard Bouzerar, Georges Bouzerar
We provide a quantitative theoretical model study of the dynamical magnetic properties of optimally annealed GaMnAs. This model has already been shown to reproduce accu…
Dynamical properties of a three-dimensional diluted Heisenberg model
Akash Chakraborty, Georges Bouzerar
We study the magnetic excitation spectrum in three-dimensional diluted ferromagnetic nearest-neighbor systems down to the percolation threshold. The disorder effects resulting from…
