Topological chiral-gain in a Berry dipole material. [PDF]
NanophotonicsAbstract Recent studies have shown that low‐symmetry conductors under static electric bias offer a pathway to realize chiral gain, where the non‐Hermitian optical response of the material is controlled by the spin angular momentum of the wave. In this work, we uncover the topological nature of chiral gain and demonstrate how a static electric bias ...

Magnetoelectric effect in bismuth - neodymium ferrite - garnet films [PDF]
IOP Conference Series: Materials Science and Engineering, 2020 Abstract The prehistory of the dielectric properties of bismuth – neodymium ferrite – garnet films on a Gd3Ga5O12 (111) substrate cooled in an electric and magnetic field were established. The dynamic characteristics of the electric polarization are studied at large times when the electric field is turned on and off.

Magnetoresistance of rare-earth-substituted garnet ferrite films
IOP Conference Series: Materials Science and Engineering, 2022 Abstract Thin epitaxial films of garnet ferrite were studied using impedance spectroscopy. The influence of the magnetic field on the transport characteristics was investigated on the basis of the current-voltage characteristic characteristics (I-V) measured without a field and in a magnetic field H = 12 kOe. An increase in resistance in
