Аннотация: X-ray, magnetic, and Mossbauer studies of a PbFe0.5Ta0.5O3 powder have been carried out. For the first time temperature dependence of the unit cell parameters was obtained. Antiferromagnetic Neel temperature T-N approximate to 180K was determined using the results of Mossbauer studies. In the vicinity of T-N an anomaly in the tempeПоказать полностьюrature dependence of the monoclinic angle beta was revealed in PFT. This anomaly seems to be due to the magnetoelectric coupling.
