Highly controllable switching pathways in multiferroic GdMnO
M. Ryzhkov, A. Granero, J. Wettstein +7
Controlling magnetic moments using electric fields remains a central challenge in spintronics. Multiferroics, where magnetic and electric orders coexist, may be a natural platform…
Nonlinear helicity anomalies in the cyclotron resonance photoresistance of two-dimensional electron systems
Erwin Mönch, Sophia Schweiss, Ivan Yahniuk +7
Our studies of the cyclotron resonance (CR) photoresistance in GaAs-based two-dimensional electron systems (2DES) reveal an anomalously low sensitivity to the helicity of the incom…
Unusual magnetoelectric effect in paramagnetic rare-earth langasite
L. Weymann, L. Bergen, Th. Kain +13
Violation of time reversal and spatial inversion symmetries has profound consequences for elementary particles and cosmology. Spontaneous breaking of these symmetries at phase tran…
Electron spin resonance in spiral antiferromagnet linarite: theory and experiment
S. K. Gotovko, L. E. Svistov, A. M. Kuzmenko +2
We present combined experimental and theoretical investigation of the low-frequency ESR dynamics in the ordered phases of magnetic mineral linarite. This material consists of weakl…
Controlling of light with electromagnons
D. Szaller, A. Shuvaev, A. A. Mukhin +2
Magnetoelectric coupling in multiferroic materials opens new routes to control the propagation of light. The new effects arise due to dynamic magnetoelectric susceptibility that cr…
Giant gigahertz optical activity in multiferroic ferroborate
A. M. Kuzmenko, A. Shuvaev, V. Dziom +6
In contrast to well studied multiferroic manganites with a spiral structure, the electric polarization in multiferroic borates is induced within collinear antiferromagnetic structu…
Electric field control of terahertz polarization in a multiferroic manganite with electromagnons
A. Shuvaev, V. Dziom, Anna Pimenov +6
All-electrical control of a dynamic magnetoelectric effect is demonstrated in a classical multiferroic manganite DyMnO3, a material containing coupled antiferromagnetic and ferroel…
Terahertz properties of Dirac fermions in HgTe films with optical doping
V. Dziom, A. Shuvaev, N. N. Mikhailov +1
Terahertz properties of mercury telluride (HgTe) films with critical thickness are presented and discussed. The density of the charge carriers is controlled using contact-free opti…
Observation of the universal magnetoelectric effect in a 3D topological insulator
V. Dziom, A. Shuvaev, A. Pimenov +9
The electrodynamics of topological insulators (TIs) is described by modified Maxwell's equations, which contain additional terms that couple an electric field to a magnetization an…
Order-disorder type critical behaviour at the magnetoelectric phase transition in multiferroic DyMnO
M. Schiebl, A. Shuvaev, Anna Pimenov +5
We present the results of detailed dielectric investigations of the relaxation dynamics in DyMnO multiferroic manganite. Strong low-frequency relaxation process near the parael…
Spectral origin of the colossal magnetodielectric effect in multiferroic DyMn2O5
A. B. Sushkov, Ch. Kant, M. Schiebl +8
The origin of the colossal magnetodielectric effect in DyMn2O5 [1] has been an outstanding question in multiferroics. Here, we report the activation of the electric dipole mode at…

A. M. Vasiliev, L. A. Prozorova, L. E. Svistov +5
Using electron-spin-resonance (ESR) technique we investigate the magnetic structure of CuCrO2, quasi-two-dimensional antiferromagnet with weakly distorted triangular lattice. Reson…
Negative refraction in natural ferromagnetic metals
Sebastian Engelbrecht, Alexey Mikhailovich Shuvaev, Y. Luo +2
It is generally believed that Veselago's criterion for negative refraction cannot be fulfilled in natural materials. However, considering imaginary parts of the permittivity (ε) an…
