We hope to establish the extents to which spin-waves and coherent magnons in antiferromagnetic insulators and ferromagnetic insulators can be strongly coupled to electric and thermal currents in adjacent conductors and utilize this coupling to control electric signals.
Also, the thermodynamic relation [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] which holds for 2nd order phase transition is violated in some materials with Bose - Einstein condensate (BEC)-like phase transition (see for example as in spin glasses [9], ferromagnetic and antiferromagnetic spin models with temperature driven transitions [10]).
This means that antiferromagnetic atom rows can be spaced much more closely without magnetically interfering with each other.
And in both groups, superconductivity appears when scientists destabilize the antiferromagnetic order--through doping or by applying pressure--and magnetic orientations within the crystal start to fluctuate, switching from up to down.
com/research/e86aa7/magnetic_propertie) has announced the addition of John Wiley and Sons Ltd's new book "Magnetic Properties of Antiferromagnetic Oxide Materials: Surfaces, Interfaces, and Thin Films" to their offering.
Objective: "The proposed HARFIR project intends to develop antiferromagnetic (AF) Heusler alloy (HA) films to replace the antiferromagnetic alloy Iridium Manganese (IrMn), which has been widely used in all spin electronic devices including hard disk drives and next-generation magnetic memories.
Antiferromagnetic materials are composed of two interpenetrating lattices.
Status Solidi B 2010, 247, 671) investigates the low-frequency spin dynamics and quantum critical behavior in the isotropic S=1/2 antiferromagnetic Heisenberg chain system copper pyrazine dinitrate (CuPzN).
Washington, Nov 26 (ANI): For the first time, researchers at the National Institute of Standards and Technology (NIST) have demonstrated the existence of a key magnetic, and not electronic, property, called antiferromagnetic coupling, of specially built semiconductor devices.
The latter is an antiferromagnetic material, meaning that neighboring atoms tend to align their magnetic orientations in opposite directions.
While the highest temperature superconductors to date are the copper oxide family of antiferromagnetic Mott insulators, the origin of unconventional superconductivity in these materials remains mysterious.
Most of the intrinsic resonant behavior in the microwave through millimeter frequency bands are due to cooperative ferromagnetic and ferrite spin-related resonances, antiferromagnetic resonances, microwave atomic transitions, plasmons and plasmon-like resonances, and polaritons at metal-dielectric interfaces.
