Temperature dependence of electrically detected ESR at filling factor ν=1 in a 2DEG

Electrically detected electron spin resonance (ESR) was measured as a function of temperature for 0.3– 4.2 K in a AlGaAs/GaAs multiple quantum well sample at filling factor ν=1. The ESR amplitude exhibits a maximum at about 2.2 K and vanishes with increased or decreased temperature. To explain the o...

Description
Summary:Electrically detected electron spin resonance (ESR) was measured as a function of temperature for 0.3– 4.2 K in a AlGaAs/GaAs multiple quantum well sample at filling factor ν=1. The ESR amplitude exhibits a maximum at about 2.2 K and vanishes with increased or decreased temperature. To explain the observed temperature dependence of the signal amplitude, the signal amplitude temperature dependence is calculated assuming a model based on heating.
