Abstract

We report on a novel diluted magnetic semiconductor based on the Sb₂Te₃ tetradymite structure doped with very low concentrations of vanadium (1–3 at%). Anisotropy in the magnetic hysteresis loops and magnetoresistance are observed at temperatures below the ferromagnetic ordering temperature. A Curie temperature of 24 K is observed for Sb_1.97V_0.03Te₃.

Defect structure of Sb<inf>2-x</inf>Fe<inf>x</inf>Te<inf>3</inf> single crystals
2007, Journal of Solid State Chemistry
Single crystals of Sb₂₋_xFe_xTe₃ (c_Fe=0–9.5×10¹⁹ cm⁻³) were prepared by Bridgman method. The interpretation of the reflection spectra in plasma resonance region indicates that Fe increases the concentration of holes (acceptor) and each Fe atom incorporated in Sb₂Te₃ structure liberates 0.4–0.5 hole. Observed effect is elucidated by means of point defect model. According to the model Fe atoms enter the structure and form uncharged substitutional defects ${Fe}_{Sb}^{\times}$ . Since this defect cannot affect the free-carrier concentration directly, we assume an interaction of the entering Fe-atoms with natives defects leading to a rise in the concentration of antisite defects ${Sb}_{Te}^{'}$ , to a decrease of $V_{Te}^{}$ concentration, and to an increase in the concentration of holes.

Moreover, low-temperature ferromagnetism and magnetic anisotropy were found in p-Bi2Te3 〈Fe〉 for very low concentrations of Fe [12–14]. Later, low-temperature ferromagnetism was found in Sb2−xVxTe3[15] and in Bi2−xMnxTe3[16], while in Bi2−xGdxTe3[17] and Sb2−xMnxTe3[18] only paramagnetic behavior was found. Low-temperature ferromagnetism was reported recently in Sb2−xCrxTe3[19].
We grew single crystals of the new dilute magnetic semiconductor p-Sb₂₋_xCr_xTe₃ ( $x = 0, 0.0115,$ $0.0215$ ) and investigated their transport, magneto-transport and magnetic properties in the temperature interval 1.7–300 K. In high fields we clearly observed Shubnikov–de Haas oscillations, that show a decrease in hole concentration for Cr-doped samples. A negative magnetoresistance and anomalous Hall effect are observed in Cr-doped samples. Ferromagnetic order is found below the Curie temperature T_c≈5.8 K ( $x = 0.0215$ ) and T_c≈2.0 K ( $x = 0.0115$ ). In the ferromagnetic phase we observe large magnetic anisotropy with the easy-axis parallel to the C₃ crystallographic axis.
