The anomalous Hall conductivity of bulk and 2D Cr<sub>2</sub>Te<sub>3</sub>

ORAL

Abstract

Chromium telluride (Cr2Te3) is an inorganic chemical compound that exhibits ferromagnetic properties (Tc=195 K) and a large perpendicular anisotropy of 7 × 105 J m−3. Recently, ferromagnetic Cr2Te3 nanorods were synthesized that exhibit hard and soft phase coexistence (Nanoscale, 2018, 10, 11028). We present the density functional study of the anomalous Hall effect of bulk and 2D Cr2Te3. The effect of magnetic texture is investigated as these layered materials show possibility of canting of the Cr moments in the ordered vacancy layers. We discuss these results in view of recent anomalous Hall effect measurement.
