Description
Summary:Interest in the MnSe1-xTex solid solutions system is caused by the possibility of the orbital ordering existence into the Torb < T < TN temperature range in MnSe and MnTe. Samples in the 0.0 ≤ x ≤ 0.4 concentration interval with the step Δx 0.1 are synthesized. It is established that all synthesized compositions possess the elementary NaCl-type cubic cell. The unit cell parameter a linearly varies from a 0.546 nm for the composition with x 0 to a 0.562 nm for x 0.4. The magnetic susceptibility temperature dependences are studied. It is determined that Neel's temperature in the investigated samples smoothly decreases from 132 K for MnSe0.9Te0.1 to 118 for MnSe0.6Te0.4 composition. Paramagnetic Curie temperature so decreases with the concentration increase from ΘP −350 for x =0.1 to ΘP -270 for x 0.4. Similarly changes the effective magnetic moment value, decreasing 5.50 Bohr magnetons for MnSe0.9Te0.1 and 5.13 Bohr magnetons for MnSe0.6Te0.4.
