Abstract: | Powder samples of FexTiSe2 (0.00 ≤ x ≤ 0.50) have been prepared by direct reaction of high purity elements. Crystal parameters were determined by the Debye-Scherrer powder diffraction technique. Magnetic susceptibility measurements were made by the Faraday method in the temperature range 1.5–300 K and indicated magnetic odering for compositions with x > 0.03. The magnetic ordering temperature, Tm, was observed to move to higher temperature with increasing iron concentration. These results have been interpreted in terms of a spin-glass model for low iron concentrations (x < 0.2) and antiferromagnetism for high concentrations (x > 0.2). |
