Multichannel Phonon Interconversion Drives 90 Polarization Rotation for Stable Domain Walls in Hafnium Oxide
Fatoye Sawyerr, Hamoon Fahrvandi, Pawan Kumar +11
Polarization rotation is a fundamental mechanism in ferroelectric materials, yet how such rotation arises microscopically in fluorite ferroelectrics and gives rise to distinct doma…
Optical diode effect in the room-temperature multiferroic BiFeO$_3
I. Kezsmarki, U. Nagel, S. Bordacs +5
Multiferroics permit the magnetic control of the electric polarization and electric control of the magnetization. These static magnetoelectric (ME) effects are of enormous interest…
Strong spin-phonon coupling in infrared and Raman spectra of SrMnO3
S. Kamba, V. Goian, V. Skoromets +9
Infrared reflectivity spectra of cubic SrMnO ceramics reveal 18 % stiffening of the lowest-frequency phonon below the antiferromagnetic phase transition occurring at T…
Coupled magnetic-ferroelectric metal-insulator transitions in epitaxially-strained SrCoO from first principles
Jun Hee Lee, Karin M. Rabe
First-principles calculations of the epitaxial-strain phase diagram of perovskite SrCoO are presented. Through combination of the large spin-phonon coupling with polarization…
Epitaxial-strain-induced multiferroicity in SrMnO from first principles
Jun Hee Lee, Karin M. Rabe
First-principles density-functional calculations reveal a large spin-phonon coupling in cubic SrMnO, with ferromagnetic ordering producing a polar instability. Through combin…
