X-Ray and Magnetic Measurements of TmFeTi₂O₇

Abstract:

In this paper we are reported about a peculiarity of the crystal structure and the magnetic state of TmFeTi₂O₇. The compound TmFeTi₂O₇has been synthesizedusing the solid-phase reaction method. Using X-ray diffraction method the disorder in the distribution of the iron ions over five nonequivalent crystal sites was observed, also the populations of the iron atoms positions were determined. We show that below T_f= 6 K the magnetization of TmFeTi₂O₇depends on the magnetic history of the sample. There are indications for spin glass state. This results allow us to assume the state of spin glass is realized below freezing temperature T_f= 6 K in TmFeTi₂O₇.
