Magnetic properties of CrTe, Cr23Te24, Cr7Te8, Cr5Te6, and Cr3Te4 compounds

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

“…The presence of Cr-related nanoclusters is known in literature to be responsible for room temperature ferromagnetism in Zn 1−x Cr x Te diluted magnetic semiconductors [10]. 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]).…”

Magnetic Order and Magnetic Inhomogeneities in SnCrTe-PbCrTe Solid Solutions

“…The magnetic susceptibility for the sample with y = 0.07 has values more than an order of magnitude higher than for y = 0.01. The temperature dependence of the magnetic susceptibility for the samples with y = 0.07 shows a paramagnetferromagnet transition located at temperatures close to 300 K. The Curie temperature, determined from the inverse of the magnetic susceptibility has a value of about 266 ± 10 K. The ferromagnetic alignment of Cr-ions in this sample is related to the presence of Cr-Te clusters detected with [15,16] with the Curie temperatures well above 300 K. The literature data show that the most probable CrTe-related clusters that could be responsible for the ferromagnetic order in this sample are Cr 5 Te 8 clusters. The dierence between the T C observed for our samples (266 K) and the values reported for Cr 5 Te 8 (190245 K) may be due to the fact that the ferromagnetic clusters are placed in diamagnetic Sn-Pb-Te matrix.…”

Anomalous Hall effect in the trigonal Cr5Te8 single crystal

“…[13][14][15] Binary chromium tellerides Cr 1−x Te are ferromagnetic with T c of 170 ∼ 360 K depending on Cr occupancy. [16][17][18][19][20][21][22] Cr 1−x Te with x < 0.1 crystallize in the hexagonal NiAs structure, while Cr 3 Te 4 (x = 0.25) and Cr 2 Te 3 (x = 0.33) form monoclinic and trigonal crystal structures where Cr vacancies occupy every second metal layer. Neutrondiffraction measurement shows that the saturation magnetization in Cr 1−x Te is small due to possible spin canting and itinerant nature of the d electrons.…”
