Determining Curie temperature of (Ga,Mn)As samples based on electrical transport measurements: Low Curie temperature case.

Forskningsoutput: TidskriftsbidragArtikel i vetenskaplig tidskrift

Abstract

In this paper, we show that the widely accepted method of the determination of Curie temperature (Tc) in (Ga,Mn)As samples, based on the position of the peak in the temperature derivative of the resistivity, completely fails in the case of non-metallic and low-TC unannealed samples. In this case, we propose an alternative method, also based on electric transport measurements, which exploits temperature dependence of the second derivative of the resistivity upon magnetic field.
