Magnetic phase transitions and magnetoelectric coupling of GdFeO_3 single crystals probed by low-temperature heat transport
arXiv:1012.3314 · doi:10.1103/PhysRevB.83.014414
Abstract
The low-temperature thermal conductivity (κ) of GdFeO_3 single crystals is found to be strongly dependent on magnetic field. The low-field κ(H) curves show two "dips" for H \parallel a and only one "dip" for H \parallel c, with the characteristic fields having good correspondence with the spin-flop and the spin-polarization transitions. A remarkable phenomenon is that the subKelvin thermal conductivity shows hysteretic behaviors on the history of applying magnetic field, that is, the κ(H) isotherms measured with field increasing are larger than those with field decreasing. Intriguingly, the broad region of magnetic field (\sim 0--3 T) showing the irreversibility of heat transport coincides with that presenting the ferroelectricity. It is discussed that the irreversible κ(H) behaviors are due to the phonon scattering by ferroelectric domain walls. This result shows an experimental feature that points to the capability of controlling the ferroelectric domain structures by magnetic field in multiferroic materials.
