The Synthesis and Investigation of the Electrical Properties of Tricadmium Diarsenide with MnAs Nanogranules

Abstract: Samples of tricadmium diarsenide with MnAs nanogranules (44.7 mol % MnAs) are synthesized. The morphology of the samples is studied by X-ray phase analysis and electron microscopy. The electrical properties of tricadmium diarsenide with MnAs nanogranules are studied in a range of temperatures of 77–372 K. It is found that the voltammetric characteristics are symmetrical relative to the inversion of the voltage sign at this temperature, and their deviation from ohmicity at a certain threshold voltage and decrease in the region of ohmicity with the growth in temperature are determined by the increase in the breakdown probability in a field above 5 × 104 V/m. © 2020, Pleiades Publishing, Ltd

Spin-polarized electric current in Cd₄₈̣.₆Mn₁₁.₄As₄₀ nanocomposite

For the first time, the temperature dependences of the electrical resistivity and magnetization of the Cd₄₈̣.₆Mn₁₁.₄As₄₀ nanocomposite were measured in the temperature range of 10-350 K. It is shown that the electrical properties of Cd₄₈̣.₆Mn₁₁.₄As₄₀ are associated with spin polarization of intrinsic electrons in the Cd3As2 matrix by spin-polarized electrons injected into it from ferromagnetic MnAs nanocluster
