Sentences with word «ferromagnetism»

In some materials, electron spins spontaneously align their direction, leading to the phenomenon of ferromagnetism which is well known e.g. in iron.

«Interestingly, we found that magnetic anisotropy is an inherent property in the 2 - D material we studied, and because of this characteristic, we were able to detect the intrinsic ferromagnetism,» said study lead author Cheng Gong, a postdoctoral researcher in Zhang's lab.

Such polarity - reversing materials are called ferroelectric (an analogy with ferromagnetism, even though iron is not involved in the electric version).

Super-strong graphene oxide (GO) sheets are useful for ultrathin, flexible nano - electronic devices, and display unique properties including photoluminescence and room temperature ferromagnetism.

Despite bookending those three elements on the periodic table, copper and manganese ordinarily don't support the coordinated electron spin that's necessary for ferromagnetism.

Lei Liang, a postdoc in Ye's research group and first author of the paper, built a device in which he could induce ferromagnetism in non-magnetic platinum, using a field effect generated by gating through an ionic medium called ionic liquid.

They can be insulating, conducting, semiconducting, superconducting and even show signs of ferromagnetism.

The scientists found that a 2 - D van der Waals crystal, part of a class of material whose atomically thin layers can be peeled off one by one with adhesive tape, possessed an intrinsic ferromagnetism.

«CGT is also a semiconductor, and the ferromagnetism is intrinsic,» said co-senior author Jing Xia, UC Irvine associate professor of physics and astronomy.

That enabled researchers to easily control the temperature at which the material loses its ferromagnetism, known as the transition or Curie temperature.

Unlike graphene, the team's material exhibits traditional magnetism, or ferromagnetism, meaning the electrons align in a parallel arrangement like the north and south poles of a typical bar magnet.

Over time, these structures likely break down, reducing the material's ferromagnetism.

Although they were named after an analogous magnetic phenomenon — ferromagnetism — ferroelectrics were generally thought to not have magnetic properties, which made me, a budding magnetism researcher, an apparently odd fit for the laboratory.

According to the researchers, this is the first definitive sign in an isolated monolayer with an intrinsic ferromagnetism.

Strong paramagnetism (not to be confused with the ferromagnetism of the elements iron, cobalt, nickel, and other alloys) is exhibited by compounds containing iron, palladium, platinum, and the rare - earth elements.

Fuhrer thinks that if vacancies in graphene could be arranged in just the right way, ferromagnetism could result.

Electric - field control of ferromagnetism.
