Optical properties of random alloys : Application to Cu_{50}Au_{50} and Ni_{50}Pt_{50}
Kamal Krishna Saha, Abhijit Mookerjee
In an earlier paper [K. K. Saha and A. Mookerjee, Phys. Rev. B 70 (2004) (in press) or, cond-mat/0403456] we had presented a formulation for the calculation of the configuration-av…
Block recursion and Green matrices
Kamal Krishna Saha, Abhijit Mookerjee
We present here generalization of the recursion method of Haydock et al [1] for the calculation of Green matrices (in angular momentum space). Earlier approaches concentrated on th…
Magnetic transition in Ni-Pt alloy Systems : Experiment and Theory
Uday Kumar, K. G. Padmalekha, P. K. Mukhopadhyay +2
We report here the preparation and measurements on the susceptibility, sound velocity and internal friction for Ni-Pt systems. We then compare these experimental results with the f…
Phase stability analysis in Fe-Pt and Co-Pt alloy systems: An augmented space study
Durga Paudyal, Tanusri Saha-Dasgupta, Abhijit Mookerjee
We have studied the problem of phase stability in Fe-Pt and Co-Pt alloy systems. We have used the orbital peeling technique in the conjunction of augmented space recursion based on…
Phase Stability in 3d-5d (NiPt and CuAu) and 3d-4d (NiPd and CuAg) Systems
Durga Paudyal, Abhijit Mookerjee
We show the differences in the stability of 3d-5d (NiPt and CuAu) and 3d-4d (NiPd and CuAg) alloys arise mainly due to relativistic corrections. The magnetic properties of disorder…
Optical properties of random alloys : A formulation
Kamal Krishna Saha, Abhijit Mookerjee
We present here a formulation for the calculation of the configuration-averaged optical conductivity in random alloys. Our formulation is based on the augmented-space theorem intro…
