Two Displacive Ferroelectric Phase Transitions in Multiferroic Quadruple Perovskite
A. Maia, M. Kempa, V. Bovtun +6
We report on the microwave, terahertz (THz), infrared and Raman spectroscopic studies of ceramics, shedding more light into the nature of two structural phase tran…
Strong impact of low-level substitution of Mn by Fe on the magnetoelectric coupling in
A. Maia, R. Vilarinho, P. Proschek +6
The correlation between static magnetoelectric coupling and magnetic structure was investigated in with magnetic field up to 8 T and down to 2 K. Single…
Modifying the magnetoelectric coupling in TbMnO by low-level Fe substitution
A. Maia, R. Vilarinho, C. Kadlec +6
We report a comprehensive study of the low-level substitution of Mn by Fe effect on the static and dynamic magnetoelectric coupling in TbMnFeO (,…
Can the Ferroelectric Soft Mode Trigger an Antiferromagnetic Phase Transition?
André Maia, Christelle Kadlec, Maxim Savinov +10
Type-II multiferroics, where spin interactions induce a ferroelectric polarization, are interesting for new device functionalities due to large magnetoelectric coupling. We report…
Raman spectroscopy of rare-earth orthoferrites RFeO3 (R = La, Sm, Eu, Gd, Tb, Dy)
Mads Christof Weber, Mael Guennou, Hong Jian Zhao +5
We report a Raman scattering study of six rare earth orthoferrites RFeO3, with R = La, Sm, Eu, Gd, Tb, Dy. The use of extensive polarized Raman scattering of SmFeO3 and first-princ…
