Magnetic properties and low temperature X-ray studies of the weak ferromagnetic monoclinic and trigonal chromium tellurides Cr5Te8

Spinodal Decomposition of Magnetic Ions in Eu-Codoped Ge1-xCrxTe

“…However, the nature of nanoclusters present in our samples seems to be dierent than the presence of CrTe related phases, such as Cr 7 Te 8 , Cr 5 Te 6 , and Cr 3 Te 4 with T C > 300 K [11], since we do not observe room temperature ferromagnetism. The magnetic properties of our samples are also dierent than the ones reported for Cr 5 Te 8 (with 190 > T C > 245 K [12]), Cr 2 Te 3 (with T C = 170 K [13]), and CrTe 2 (with T C = 18 K [14]). It is more probable that the large size of our inhomogeneities and high carrier concentration, n > 10 20 cm −3 , can cause the long range itinerant carrier-mediated magnetic interactions to be the most signicant in our samples.…”

“…The binary chromium chalcogenides and their pseudobinary substitution derivatives have received much interest because of a rich variety of magnetic and transport property [1][2][3][4][5][6][7][8][9][10][11][12]. Some of them are predicted to be excellent candidates for half-metallic ferromagnets that are seen as a key ingredient in future high-performance spintronic devices [1].…”

“…After having studied the crystal structures of Cr 57x Te 8 [6], Cr 5.095 Se 8 [7], and Cr 5+y S 8 [8], we started to investigate their physical properties [9]. Furthermore, we are exploring the influence of anion-and cation-substitution in Cr 57x Te 8 onto crystal structure and physical properties and electronic structure.…”
