This tutorial will provide a broad introduction to the nature of the magneto-optic effects in magnetic materials and their applications, with particular emphasis on devices for optical communicatio

Transitions between the Landau levels of the lowest electron and hole sub-bands have been observed in the inter-band optical absorption of a modulation doped Ga(.47)In(.53)As-Al(.48)In (.52)As supe

We have carried out a magneto-optical investigation of the 2D electron gas in the extreme quantum limit.

We have carried out a magneto-optical investigation of the 2D electron gas in the extreme quantum limit.

We study the magneto-transport properties of a quasi-1-d GaAs- Al sub x Ga sub (1-x) As ring of mobility 40,000cm sup 2/Vs at 4K.

We present a theory of the collective excitation spectrum in the fractional quantum Hall effect which is closely analogous to Feynman's theory of superfluid helium.

The fractional quantum Hall effect is a remarkable macroscopic quantum phenomenon occurring in the two-dimensional electron gas (inversion layer) at high magnetic fields and low temperatures.

We have measured the low temperature susceptibility and specific heat of the compound UIrGe and find both an antiferromagnetic phase transition at 16K and a high temperature electronic specific h

Gauge invariant approximations are used to derive all diagrams for the current response function to lowest order in the superconducting pair fluctuations.

We report on the effects of spin fluctuations, magnetic ordering, and external magnetic field on the dielectric constant of the ferromagnet SeCuO3, and the antiferromagnet TeCuO3.
