Magnetic-field-induced phase transition in Tb0.95Bi0.05MnO3+δ multiferroic
E. I. Golovenchits, V. A. Sanina Ioffe Physico-Technical Institute, Russian Academy of Sciences
Abstract:
The effect of a magnetic field on the dielectric properties of Tb0.95Bi0.05MnO3+δ single crystals has been analyzed. It has been shown that the state of the crystal for temperatures of 5–440 K is inhomogeneous and restricted domains of polar and spin correlations are exhibited in it. A phase transition in which the inhomogeneous state of the crystal changes substantially has been observed at a temperature of T ≃ 180 and 225 K (in the absence and presence of a magnetic field, respectively). The high-temperature phase contains large dielectric domains with a high dielectric constant (ε ~ 105) and thin conducting layers at the boundaries of these domains. The magnetic field significantly affects the state of both low-and high-temperature phases of the crystal, shifting the temperature of the phase transition between them, and induces an additional phase transition at T ≃ 441 K.
