antiferromagnetic system
1Antiferromagnetic interaction — An anti ferromagnetic interaction acts to anti align neighboring spins. If the energy is expressed as the sum of all pairs, i, j, over an interaction term J(i,j), times the spin of atom i times the spin of atom j, J0 is an antiferromagnetic… …
2Spin polarized scanning tunneling microscopy — (SP STM) is a specialized application of scanning tunneling microscopy (STM) that can provide detailed information of magentic phenomena on the single atom scale additional to the atomic topology gained with STM. SP STM was developed by Roland… …
3Exchange Bias — Als Exchange Bias (EB) bezeichnet man eine unidirektionale Anisotropie (deshalb auch unidirectional exchange anisotropy genannt), die durch die Kopplung zwischen einem Ferro und einem Antiferromagneten entsteht. Der Exchange Bias bewirkt eine… …
4High-temperature superconductivity — Unsolved problems in physics What causes superconductivity at temperatures above 50 kelvin? High temperature superconductors (abbreviated high Tc or HTS) are materials that have a superconducting transition temperature (Tc) above 30 K… …
5crystal — crystallike, adj. /kris tl/, n., adj., v., crystaled, crystaling or (esp. Brit.) crystalled, crystalling. n. 1. a clear, transparent mineral or glass resembling ice. 2. the transparent form of crystallized quartz. 3. Chem., Mineral. a solid body… …
6Crystal — /kris tl/, n. 1. a city in SE Minnesota, near Minneapolis. 25,543. 2. a female given name. * * * I Any solid material whose atoms are arranged in a definite pattern and whose surface regularity reflects its internal symmetry. Each of a crystal s… …
7Ising model — The Ising model, named after the physicist Ernst Ising, is a mathematical model in statistical mechanics. It has since been used to model diverse phenomena in which bits of information, interacting in pairs, produce collectiveeffects.Definition… …
8magnetism — /mag ni tiz euhm/, n. 1. the properties of attraction possessed by magnets; the molecular properties common to magnets. 2. the agency producing magnetic phenomena. 3. the science dealing with magnetic phenomena. 4. strong attractive power or… …
9Curium — This article is about the chemical element. For the ancient city located in Cyprus, see Kourion. americium ← curium → berkelium …
10Geometrical frustration — is a phenomenon in condensed matter physics in which the geometrical properties of the atomic lattice forbid the existence of a unique ground state, resulting in a nonzero residual entropy. The most important consequence of this is that the… …
