Abstract

We investigate the structural and critical properties of CrTe1−xSbx with 0.0 ≤ x ≤ 0.2. The XRD patterns revealed that Sb substitution resulted in a pure NiAs-hexagonal structure with P63/mmc (194) space group. Lattice refinement of the structure revealed little changes in the a-lattice parameter, along with a more pronounced reduction in the c-axis. The critical behavior in CrTe1−xSbx has been investigated using the magnetization isotherms near the ferromagnetic transition. The obtained critical exponents (β,γ,andδ) revealed that all samples (with 0.0 ≤ x ≤ 0.2) closely follow a mean field-like behavior with ferromagnetic Curie temperature near room temperature. The results from Widom scaling relation indicate self-consistency of the acquired values. Moreover, the magnetization isotherms near the Curie temperature follow a universal scaling behavior, giving further support for the obtained critical exponents.
