Ferro- and antiferromagnetic coupling in a chlorido-bridged, tetranuclear Cu(II) complex.
A bispidine-like ligand involving four pyridine-N and three aliphatic-N donor atoms forms a bimetallic species with CuCl2 in which all seven N-donors are bound and which aggregates in the crystal through double chloride-bridging to give a tetranuclear unit. The magnetism of this solid can be interpreted in terms of a relatively weak antiferromagnetic coupling between the two Cu(ii) centres of t...
متن کاملTheoretical description of the magnetic properties of μ3-hydroxo bridged trinuclear copper(II) complexes.
A theoretical study of the magnetic properties, using density functional theory, of a family of trinuclear μ3-OH copper(II) complexes reported in the literature is presented. The reported X-ray crystal structures of [Cu3(μ3-OH)(aat)3(H2O)3](NO3)2 · H2O (HUKDUM), where aat: 3-acetylamine-1,2,4-triazole; [Cu3(μ3-OH)(aaat)3(H2SO4)(HSO4)(H2O)] (HUKDOG), where aaat: 3-acetylamine-5-amine-1,2,4-triaz...
متن کاملExchange bias effect of ferro-/antiferromagnetic heterostructures
The exchange bias (EB) effect was discovered 60 years ago by Meiklejohn and Bean. Meanwhile the EB effect has become an integral part of modern magnetism with implications for basic research and for numerous device applications. The EB effect was the first of its kind which relates to an interface effect between two different classes of materials, here between a ferromagnet and an antiferromagn...
متن کاملThe ferro / antiferromagnetic q - state Potts model
The critical properties of the mixed ferro/antiferromagnetic q-state Potts model on the square lattice are investigated using the numerical transfer matrix technique. The transition temperature is found to be substantially lower than previously found for q = 3. It is conjectured that there is no transition for q > 3, in contradiction with previous results.
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
