Abstract

The specific magnetization and magnetic susceptibility of ferrogarnets of the composition Y_3–xCe_x(Fe_0.5Ga_0.5)₅O₁₂ (x = 0; 0.5) obtained by the gel combustion method have been measured. It has been found that after synthesis and subsequent crystallization at pressure ≈ 10^–2 Pa at 1023 K for 2 h, the temperature of magnetic phase transformation in the studied compositions Y_3–xCe_x(Fe_0.5Ga_0.5)₅O₁₂ increases with the replacement of yttrium ions Y³⁺ by Ce³⁺. In this case, the effective Curie–Weiss temperature Ɵ_eff of the antiferromagnetic component of exchange magnetic interactions in Y_2.5Сe_0.5Fe_2.5Ga_0.5O₁₂ varies from |–570| to |–650| K.

Y3-xCex(Fe0.5Ga0.5)5O12 (х = 0, 0.5) 的合成、晶体结构和磁性能

摘要测量了凝胶燃烧法获得的成分为 Y3-xCex(Fe0.5Ga0.5)5O12（x = 0；0.5）的铁榴石的比磁化率和磁感应强度。研究发现，在 1023 K 的压力≈ 10-2 Pa 条件下合成并结晶 2 小时后，所研究成分 Y3-xCex(Fe0.5Ga0.5)5O12 的磁性相变温度随着钇离子 Y3+ 被 Ce3+ 取代而升高。在这种情况下，Y2.5Сe0.5Fe2.5Ga0.5O12 中交换磁相互作用反铁磁成分的有效居里-韦斯温度 Ɵeff 从 |-570| 到 |-650| K 不等。
