The Evolution of the Magnetic Properties of Iron Borate Single Crystals Doped with Gallium

Highly perfect FeBO 3 and Fe 0.91 Ga 0.09 BO 3 single crystals were studied in a wide temperature range using SQUID magnetometry. A theoretical model describing the temperature and field dependences of the magnetization of single crystals has been developed. It is found that even a small concentrati...

Summary:Highly perfect FeBO 3 and Fe 0.91 Ga 0.09 BO 3 single crystals were studied in a wide temperature range using SQUID magnetometry. A theoretical model describing the temperature and field dependences of the magnetization of single crystals has been developed. It is found that even a small concentration of gallium, which is a diamagnetic impurity, substantially affects the magnetic properties of single FeBO 3 crystals. In particular, the Fe 0.91 Ga 0.09 BO 3 crystal differs from the pure FeBO 3 phase in by a lower magnetic phase transition temperature and a higher antiferromagnetic susceptibility at low temperatures.
