The Mutual Embrace of Electricity and Magnetism - fflch-usp
... In this picture it is apparent that the quantity of the current would depend on how many lines of tension were undergoing breakup and recombination; that is, on the size of the plates or on the number of lines through any lateral section cutting all of them. Similarly, the power of the current to ov ...

INTERACTION OF ELECTROMAGNETIC RADIATION - if
... Both effects are currently discussed mostly as applied to e-m radiation belonging to the γ-range. They depend crucially on the deviation of the photon dispersion curve from the customary shape it has in empty vacuum, k02 = |k|2 , where k0 is the photon energy, and k is its momentum. As long as one r ...

Multiferroics
Multiferroics have been formally defined as materials that exhibit more than one primary ferroic order parameter simultaneously (i.e. in a single phase), and many researchers in the field consider materials to be multiferroics only if they exhibit coupling between primary order parameters. However, the definition of multiferroics can be expanded to include non-primary order parameters, such as antiferromagnetism or ferrimagnetism.The four basic primary ferroic order parameters areferromagnetismferroelectricityferroelasticityferrotoroidicityThe last is a topic of some debate, as there was no evidence for switching ferrotoroidicity until recently.Many multiferroics are transition metal oxides with perovskite crystal structure, and include rare-earth manganites and -ferrites (e.g. TbMnO3, HoMn2O5, LuFe2O4 and recently, ""PZTFT"",). Other examples are the bismuth compounds BiFeO3 and BiMnO3, non-perovskite oxide LiCu2O2, and non-oxides such as BaNiF4 and spinel chalcogenides, e.g. ZnCr2Se4. These alloys show rich phase diagrams combining different ferroic orders in separate phases.Apart from single phase multiferroics, composites and heterostructures exhibiting more than one ferroic order parameter are studied extensively. Some examples include magnetic thin films on piezoelectric PMN-PT substrates and Metglass/PVDF/Metglass trilayer structures.Besides scientific interest in their physical properties, multiferroics have potential for applications as actuators, switches, magnetic field sensors or new types of electronic memory devices.
