antiferromagnetic
41Orthoferrite — An orthoferrite is any of a class of chemical compounds with the formula RFeO3 (where R is one or more rare earth elements). Orthoferrites have an orthorhombic crystal structure with a space group Pbnm and most are weakly ferromagnetic.[1] At the …
42Magnetochemistry — is concerned with the magnetic properties of chemical compounds. Magnetic properties arise from the spin and orbital angular momentum of the electrons contained in a compound. Compounds are diamagnetic when they contain no unpaired electrons.… …
43Hematite — For other uses, see Hematite (disambiguation). Hematite Hematite (blood ore) from Michigan (unknown scale) General Category …
44Paramagnetism — is a form of magnetism which occurs only in the presence of an externally applied magnetic field. Paramagnetic materials are attracted to magnetic fields, hence have a relative magnetic permeability greater than one (or, equivalently, a positive… …
45Ferrimagnetic interaction — A ferrimagnetic interaction is a specific type of antiferromagnetic interaction in which the net spin of the system is not equal to zero due to the spin in each direction not being equal, and therefore not cancelling. A classic example is a… …
46RKKY interaction — RKKY stands for Ruderman Kittel Kasuya Yosida and refers to a coupling mechanism of nuclear magnetic moments or localized inner d or f shell electron spins in a metal by means of an interaction through the conduction electrons. The RKKY… …
47Single-molecule magnet — Single molecule magnets or SMMs are a class of metalorganic compounds, that show superparamagnetic behavior below a certain blocking temperature at the molecular scale. In this temperature range, SMMs exhibit magnetic hysteresis of purely… …
48Heusler alloy — A Heusler alloy is a ferromagnetic metal alloy based on a Heusler phase. Heusler phases are intermetallics with particular composition and face centered cubic crystal structure. They are ferromagnetic even though the constituting elements are not …
49Organic superconductor — In physical chemistry and condensed matter physics, an organic superconductor is an organic compound which exhibits superconductivity at low temperatures. As of 2007 the highest achieved critical temperature for an organic superconductor at… …
50Heisenberg model (quantum) — The Heisenberg model is a statistical mechanical model used in the study of critical points and phase transitions of magnetic systems, in which the spin of the magnetic systems are treated quantum mechanically. In the prototypical Ising model,… …
