Chromium telluride (Cr2Te3) is an inorganic chemical compound. It is composed of the
anion. It has a shadowy gray color, and has a hexagonal crystal structure
.
Properties
Thermodynamic
Chromium telluride samples that are highly saturated with tellurium were found to crystallize in a hexagonal structure, but trigonal lattice distortions are also possible.[1][2]
Magnetic
Chromium telluride is strongly
vibrating sample magnetometry, and other physical property measurements. RHEED patterns indicate the flat, smooth growth of chromium telluride film. STM testing shows that the surface atoms of the compound arrange themselves in a hexagonal pattern. The Curie temperature was found to be 180 K[4] When transitioning between paramagnetic and ferromagnetic forms of magnetism, the surrounding magnetic field collapse into two independent curves with a sole scaling equation.[5] However, chromium telluride can still continue with a reversal of magnetism.[6]
When being measured at room temperature, the anomalous
Hall voltage of chromium telluride seems to consist of both negative anomalous and positive normal component. The negative anomalous component exhibits saturation against the intensity of the magnetic field, while the positive normal component can be ascribed to hole conduction. This is measured from room temperature to 400 °C with a-c sample current and d-c magnetic field.[7]
