The first material where an intrinsic linear magnetoelectric effect was predicted theoretically and confirmed experimentally was Cr 2 O 3. [8] [9] This is a single-phase material. Multiferroics are another example of single-phase materials that can exhibit a general magnetoelectric effect [11] if their magnetic and electric orders are coupled.
In addition, other types of primary order, such as ferroic arrangements of magnetoelectric multipoles [2] of which ferrotoroidicity [3] is an example, were proposed. Besides scientific interest in their physical properties, multiferroics have potential for applications as actuators, switches, magnetic field sensors and new types of electronic ...
The presence of a magnetic toroidic dipole moment T in condensed matter is due to the presence of a magnetoelectric effect: Application of a magnetic field H in the plane of a toroidal solenoid leads via the Lorentz force to an accumulation of current loops and thus to an electric polarization perpendicular to both T and H.
A magneto-optic effect is any one of a number of phenomena in which an electromagnetic wave propagates through a medium that has been altered by the presence of a quasistatic magnetic field. In such a medium, which is also called gyrotropic or gyromagnetic , left- and right-rotating elliptical polarizations can propagate at different speeds ...
For example, mirror symmetry can always be expressed as = ... This term leads to several interesting predictions including a quantized magnetoelectric effect. [14]

Maybe it’s parallel universes or time travel, maybe it’s just bad memory — either way, it’s fascinating.View Entire Post ›
The massless fermions lead to various quantum Hall effects, magnetoelectric effects in topological materials, and ultra high carrier mobility. [10] [11] Dirac cones were observed in 2008-2009, using angle-resolved photoemission spectroscopy (ARPES) on the potassium-graphite intercalation compound KC 8 [12] and on several bismuth-based alloys ...
