Ferroelectric polarization and magnetic structure in Eu0.595Y0.405MnO3Eu0.595Y0.405MnO3
چکیده انگلیسی

A neutron diffraction study was performed on a single crystal of 4f4f-moment-free perovskite manganite Eu0.595Y0.405MnO3 to elucidate the relation between the spontaneous ferroelectric polarization and the magnetic structure. Eu0.595Y0.405MnO3 shows an incommensurate magnetic ordering below TN=47K. The ferroelectric polarization P along the c axis appears below 25 K, and it is replaced by P along the a axis below 23 K. We have observed the change of magnetic structure at temperatures where the ferroelectric polarization appears and changes its polarization direction.
