Magnetic short and long range order in PbFe $_{1/2}$ Ta $_{1/2}$ O $_{3}$

Abstract

PbFe $_{1/2}$ Ta $_{1/2}$ O $_{3}$ (PFT) belongs to the family of PbB $_{x}^{'}$ B $"_{1 - x}$ O $_{3}$ which have inherent chemical disorder at the B-site. Due to this disorder, a complex magnetic phase diagram is expected in the material. In this paper, we report experimental results of magnetic properties in PFT through macroscopic characterization, neutron scattering and Mössbauer spectroscopy techniques. With these results we show for the first time that PbFe $_{1/2}$ Ta $_{1/2}$ O $_{3}$ behaves very similar to PbFe $_{1/2}$ Nb $_{1/2}$ O $_{3}$ , i.e, it undergoes AF transition at 153 K and has a spinglass transition at 10 K, below which the antiferromagnetism coexists with spinglass. We suggest that the mechanism which is responsible for such a non-trivial ground state can be explained by a speromagnet-like spin arrangement similar to the one proposed for PbFe $_{1/2}$ Nb $_{1/2}$ O $_{3}$ .
