Exempel på hur man kan använda PARAMAGNETISM i en mening

• In addition, a nonuniform magnetic field exerts minuscule forces on "nonmagnetic" materials by three other magnetic effects: paramagnetism, diamagnetism, and antiferromagnetism, although these forces are usually so small they can only be detected by laboratory equipment.
• On top of the applied field, the magnetization of the material adds its own magnetic field, causing the field lines to concentrate in paramagnetism, or be excluded in diamagnetism.
• If the materials are not hard, Braunbeck's extension shows that materials with relative magnetic permeability greater than one (paramagnetism) are further destabilising, but materials with a permeability less than one (diamagnetic materials) permit stable configurations.
• An applied magnetic field can flip the magnetic dipoles that make up the material causing both paramagnetism and ferromagnetism.
• Langevin is noted for his work on paramagnetism and diamagnetism, and devised the modern interpretation of this phenomenon in terms of spins of electrons within atoms.
• This value results from the competition of two contributions: a diamagnetic contribution (known as Landau's diamagnetism) coming from the orbital motion of the electrons in the presence of a magnetic field, and a paramagnetic contribution (Pauli's paramagnetism).
• Crystal field theory may be used to explain the relative stabilities of transition metal compounds of different coordination geometry, as well as the presence or absence of paramagnetism, whereas VSEPR may be used for complexes of main group element to predict geometry.
• He also worked at the field of the transition metals and fusions superconductivity in particular he studied the problem of simultaneity of ferromagnetism and paramagnetism.
• Zintl phases are a subgroup of brittle, high-melting intermetallic compounds that are diamagnetic or exhibit temperature-independent paramagnetism and are poor conductors or semiconductors.
• LSM has a rich electronic phase diagram, including a doping-dependent metal-insulator transition, paramagnetism and ferromagnetism.
• Only elements with unpaired electrons exhibit paramagnetism, ferromagnetism, and antiferromagnetism.
• In magnetochemistry, the need for a double group arises in a very particular circumstance, namely, in the treatment of the paramagnetism of complexes of a metal ion in whose electronic structure there is a single electron (or its equivalent, a single vacancy) in a metal ion's d- or f- shell.
• Therefore, it is possible to use this diamagnetism to differentiate calcifications from iron deposits that usually demonstrate strong paramagnetism.
• It is suggested that the unusual small diamagnetic susceptibility observed for SWNHs is due to the cancellation of expected large diamagnetism by Van Vleck paramagnetism.
• 1928–1930 – John Hasbrouck Van Vleck formalizes the quantum theory of magnetism and formulates Van Vleck paramagnetism.
• This suggests that the cyclooctatetraene ligands are highly fluxional and some degree of paramagnetism.
