Shubnikov-de-Haas oscillation and possible modification of effective mass in CeTe3 thin films

Magnetoresistance measurements have been performed in CeTe3 thin film devices in a temperature range from 2.1 to 20 K up to 8 T. A clear Shubnikov-de-Haas oscillation was observed in the whole temperature range. The temperature dependence of the oscillation amplitude was found to deviate from the Lifshitz-Kosevich formula below the magnetic transition temperature at T-N1 approximate to 3 K. This indicates a significant interplay between the magnetic ordering and the conduction electrons, which could lead to a modification of the effective cyclotron mass. By analyzing the temperature dependence of the oscillation amplitude, we have estimated the effective mass, quantum lifetime and quantum mobility of the material both in the paramagnetic and antiferromagnetic states.

Automated summary

Magnetoresistance measurements in CeTe3 thin film devices revealed a significant interplay between magnetic ordering and conduction electrons, affecting the effective cyclotron mass and other properties of the material. Analysis of the temperature dependence of the oscillation amplitude provided insights into the material's characteristics in both paramagnetic and antiferromagnetic states.
