Emerging routes to multiferroics

Multiferroics : Past , present , and future

© 2010 American Institute of Physics, S-0031-9228-1010-020-9 The interplay between electricity and magnetism has fascinated scientists and engineers for centuries, ever since Hans Christian Oersted noticed in 1820, quite by accident, that a magnetic compass needle deflected when he switched the current in a nearby battery on or off. Over the 40 years or so following Oersted’s observation, the c...

Electromagnon excitations in canted-spin multiferroics

An organic approach for nanostructured multiferroics.

Multiferroics are materials that simultaneously exhibit more than one ferroic order parameters, such as ferroelectricity, ferroelasticity and ferromagnetism. Recently, multiferroicity has received a significant revival of interest due to the colossal magnetoelectric coupling effect for the development of nano-ferronics. In this mini-review, we focus on a recent study of ferroelectricity, magnet...

Routes to greener plastics

How to hide a dimension from view Compacted dimensions are essential ingredients of advanced string theories; the extra dimensions used to describe the world are hidden from view, or compacted. Pendry et al. used concepts of transformation optics, in which metamaterials are designed to produce specific optical properties, to show theoretically that compacted dimensions could be possible in plas...
