adjective
- of or relating to the induction of electric current or electromotive force by means of permanent magnets.
Word History and Origins
Origin of magnetoelectric1
Example Sentences
They convert energy from a magnetic field into a mechanical oscillation and subsequently into an electric current by means of an effect known as the composite magnetoelectric effect.
A team of researchers led by Associate Professor Kenta Kimura of the Graduate School of Engineering at Osaka Metropolitan University investigated the phenomenon of nonreciprocal optical absorption in the magnetoelectric antiferromagnet LiNiPO4 at shortwave infrared wavelengths.
"With that question in mind, we thought that magnetoelectric materials were ideal candidates for use in neurostimulation. They respond to magnetic fields, which easily penetrate into the body, and convert them into electric fields -- a language our nervous system already uses to relay information."
The researchers started with a magnetoelectric material made up of a piezoelectric layer of lead zirconium titanate sandwiched between two magnetorestrictive layers of metallic glass alloys, or Metglas, which can be rapidly magnetized and demagnetized.
"For all other magnetoelectric materials, the relationship between the electric field and the magnetic field is linear, and what we needed was a material where that relationship was nonlinear," Robinson said.
