Resistivity model for both paramagnetic and ferromagnetic phases

Arulsamy, Andrew Das

Original · EN

The resistivity, ρ as a function of temperature and ionization energy (doping) and magnetization respectively is derived with further confinements from spin-disorder scattering. The computed Tcrossover below TC and carrier density in Ga₁₋ₓMnₓAs system are 8-12 K and 10¹⁹ cm⁻³, remarkably identical with the experimental values of 10-12 K and 10¹⁸-10²⁰ cm⁻³ respectively.
