Abstract:
The magnetic, magnetoelectric, and magnetoelastic properties of a PrFe3(BO3)4 single crystal and the phase transitions induced in this crystal by the magnetic field are studied both experimentally and theoretically. Unlike the previously investigated ferroborates, this material is characterized by a singlet ground state of the rare-earth ion. It is found that, below TN=32 K, the magnetic structure of the crystal in the absence of the magnetic field is uniaxial (l‖c), while, in a strong magnetic field H‖c (Hcr∼43 kOe at T=4.2 K), a Fe3+ spin reorientation to the basal plane takes place. The reorientation is accompanied by anomalies in magnetization, magnetostriction, and electric polarization. The threshold field values determined in the temperature interval 2–32 K are used to plot an H−T phase diagram. The contribution of the Pr3+ ion ground state to the parameters under study is revealed, and the influence of the praseodymium ion on the magnetic and magnetoelectric properties of praseodymium ferroborate is analyzed.
