Multiferroics permit the magnetic control of the electric polarization and the electric control of the magnetization. These static magnetoelectric (ME) effects are of enormous interest: The ability to read and write a magnetic state current-free by an electric voltage would provide a huge technological advantage. Dynamic or optical ME effects are equally interesting, because they give rise to unidirectional light propagation as recently observed in low-temperature multiferroics. This phenomenon… Expand

TLDR
This report reports an integrated terahertz isolator based on the magneto-optical effect of a nonreciprocal resonator that will not only inspire more solutions for integrated terAhertz non reciprocal devices, but also have the feasibility for practical applications such as teraHertz sensing and reducing unnecessary reflections in tera hertz systems.

Emergence of two-magnon modes below spin-reorientation transition and phonon-magnon coupling in bulk BiFeO3: An infrared spectroscopic study
Abstract We have studied the low-temperature magnetic and infrared data of the BiFeO3 ceramic sample to investigate the behavior of phonons and magnon-phonon coupling below 300 K. From the magneticExpand

Magnetic control of transverse electric polarization in BiFeO₃.
TLDR
High-field experiments on high-quality mono-domain BiFeO3 crystals reveal substantial electric polarization orthogonal to the widely recognized one along the trigonal c axis, which appears to couple with the domains of the cycloidal spin order and, hence, can be controlled using magnetic fields.
