antiferromagnetism

Definitions

from Wiktionary, Creative Commons Attribution/Share-Alike License

  • n. a phenomenon, similar to ferromagnetism, in which magnetic domains line up in a regular pattern, but with neighbouring electron spins pointing in opposite directions; materials showing this effect are either ferrimagnetic or diamagnetic, and become paramagnetic above the Neel temperature

  • n. magnetic field creates parallel but opposing spins; varies with temperature

  • This realization of a strongly correlated quantum gas has triggered an avalanche of work at the interface between atomic physics and condensed matter physics, with the prospect of quantum simulators for elusive phenomena ranging from antiferromagnetism to high Tc superconductivity.

  • Kittel in particular fostered my interest in linebroadening problems and introduced Wannier and me to antiferromagnetism, while Wannier taught me many fundamental techniques, and Herring put me in touch with the ideas of Landau and Mott and kept us all abreast of the literature in general.

  • The quantum critical point that plays a key role in high-temperature superconductivity is the tipping point that marks a shift to antiferromagnetism, a magnetic state that has markedly different subatomic characteristics from ferromagnetism.

  • Because of the key role in high-temperature superconductivity, most studies in the field have focused on antiferromagnetism.

  • "In contrast, the parent compounds of pnictides are metallic, but like the undoped cuprates they exhibit a quantum magnetic property called antiferromagnetism."

    EurekAlert! - Breaking News

  • Based on what's known about electron-electron interactions and about antiferromagnetism in other metals, the authors created a theoretical framework to explain the behavior of the pnictides, offering some specific predictions about how they will behave as they change phases.

  • As the temperature continued to drop, something interesting happened around 134 K. Instead of all pointing in one direction, the electron spins on neighbouring atoms lined up in opposite directions – a phenomenon called antiferromagnetism.
