Strong impact of low-level substitution of Mn by Fe on the magnetoelectric coupling in TbMnO3
Original language description
The correlation between static magnetoelectric coupling and magnetic structure was investigated in TbMn0.98Fe0.02O3 with magnetic field up to 8 T and down to 2 K. Single crystal neutron diffraction experiments reveal a substantial increase in the temperature dependence of the incommensurate modulation wavevector of the antiferromagnetic phase, as the magnetic field strength increases. Magnetic field dependent pyroelectric current measurements revealed significantly higher magnetoelectric coupling at magnetic fields below 4 T than in pure TbMnO3. This is due to the higher sensitivity of the incommensurably modulated cycloid structure to weak magnetic fields. It shows that a small 2% substitution of Mn3+ by Fe3+ has strong impact on the magnetic structure, promoting the destabilization of the incommensurably modulated magnetic cycloidal structure of TbMnO3 in a magnetic field above 5 T.
