Magnetic Susceptibility Measurements - Chemistry LibreTexts

Feb 03, 2021· κ is the magnetic susceptibility per unit volume, (I/H). The determination of a magnetic susceptibility depends on the measurement of B/H. Experimentally the Gouy method involves measuring the force on the sample by a magnetic field and is dependent on the tendency of a sample to concentrate a magnetic field within itself.

Magnetic Susceptibility - La Salle University

The effective magnetic moment is a combination of spin (moment due to unpaired electrons) and the orbit (moment due to orbital angular momentum) terms. Spin-orbit coupling arises in equivalent, degenerate orbitals which, in the presence of a magnetic field allow electrons to revolve about an axis ( e.g. dx 2-y 2 and d xy lie in the xy plane and
