Webbtheory, on the other hand, there is a non-zero diamagnetic effect, as was first shown by Landau (1930). The new features introduced by the quantum theory are twofold. First, the energy states of an electron in the presence of a magnetic field are not the same as the energy states in the absence of a field, and one may say that the radii WebbLACK OF DIAMAGNETISM AND THE LITTLE–PARKS EFFECT 9 By perturbation theory it holds that d dB λ 1,H m(B) = Z R o 1 Br2 2 −m u(r)2rdr, (3.3) where udenotes the eigenfunction corresponding to λ ... http://lscollege.ac.in/sites/default/files/e-content/Langevin%20th%20of%20diamagnetism%20lec-1.pdf imperviously definition

The molecular orbitals are written as linear combinations of gauge … WebbDiamagnetism is a repulsive property that arises from Lenz’s law. Lenz’s law says that creating a magnetic field will move electrons. Moving electrons also creates a magnetic field, and the newly created magnetic field will oppose the original one. This holds true even for electrons on an atom.

WebbLangevin’s Theory of Diamagnetism On the basis of electron theory Langevin in 1905, proposed a theory to explain the diamagnetism.
