Europium(II) titanate

[2] This compound received more attention at the beginning of the 21st century (2001 to 2015) due to the low-temperature phase transition to antiferromagnetic behavior at TN = 5.5 K, which has a significant influence on the dielectric constant.

[3][4][5] Dried Eu2O3 and Ti2O3 are mixed 1:1 and reacted in an argon atmosphere at 1400 °C:[3] The europium is reduced and the titanium is oxidized.

Europium(II) titanate has two different crystal forms depending on the temperature.

The phase transition occurs at 282 K.[3][6] The low temperature form crystallizes in the tetragonal space group I4/mcm (space group No.

[8] The compound becomes G-type antiferromagnetic below 5.5 K.[9] The specific heat capacity is 125 J·mol−1·K−1 (at 600 K).
