摘要

研究了La1 - xSrxFeO3 - δ样品（x = 0.33, 0.50和0.67）磁化强度的温度依赖性。测定了它们的尼尔温度TN，在此温度下，样品中存在非共线反铁磁性（弱铁磁性）。在La1 - xSrxFeO3 - δ中引入锶取代杂质，使其含量增加，导致TN显著降低。这种影响可以用真空热处理来补偿，相反，观察到TN明显增加。

Effect of Vacuum Heat Treatment on Magnetic Ordering in Substituted Orthoferrite La1 – xSrxFeO3 – δ

The temperature dependences of the magnetization of La_{1 –} _xSr_xFeO_{3 – δ} samples (x = 0.33, 0.50, and 0.67) have been studied. Their Neel temperatures T_N have been determined, at which non-collinear antiferromagnetism (weak ferromagnetism) is settled down in the samples. The introduction of a substituting impurity of strontium into La_{1 –} _xSr_xFeO_{3 – δ} and an increase in its content results in a considerable decrease in T_N. This effect can be compensated using vacuum heat treatment, upon which, on the contrary, a noticeable increase in T_N is observed.
