Electrical Resistance and Magnetoresistance of Cd3As2–30 mol % MnAs under High Pressures

Year: 2021

Type: article

Abstract: The paper presents the results of a study on the Electrical resistance and magneto-resistance (MR) of the composite, consisting of a Dirac semimetal Cd3As2 and 30 mol % ferromagnetic dopand MnAs at pressure values up to 50 GPa. In the pressure range of 16–50 GPa, a hysteresis behavior of the transport properties was observed during a cycle of application and release of a pressure. Measurements on MR in the pressure rise and release mode revealed the features in the form of maxima of negative and positive MR, when the relative magneto-resistance (ΔR/R0) reached ~20% and ~5.3% for negative and positive values respectively. An instability of the monoclinic structure of Cd3As2 as a result of its partial decomposition during decompression has been established.
