The spin excitation gap (Es) at odd integer filling factors ν=1, 3, 5, 7, 9, 11, 13 has been determined using transport measurements. The gap is dominated by the exchange energy (Ex) even for the highest filling factor investigated. The variation of

Magneto-transport measurements have been used to investigate the band structure and crystal-field splitting of a thin TmAs epitaxial layer buried in GaAs. From the Fourier transform of the Shubnikov-de Haas oscillations we estimate an exchange energy

We have studied the magnetic properties of self-organized ErAs aggregates embedded in a GaAs matrix using telegraph noise spectroscopy. The electrical transport through the samples is mesoscopic and exhibits universal conductance fluctuations and two

The infrared (900-1100 cm(-1)) Faraday rotation and circular dichroism are measured in the normal state of underdoped High T(c) superconductors and used to study the magnetotransport. YBa2Cu3O6+x thin films are investigated in the temperature range 1

A sensitive polarization modulation technique uses photoelastic modulation and hetrodyne detection to simultaneously measure the Faraday rotation and induced ellipticity in light transmitted by semiconducting and metallic samples. The frequencies mea

We measure the temperature and frequency dependence of the complex Hall angle for normal state YBa$_2$Cu$_3$O$_7$ films from dc to far-infrared frequencies (20-250 cm$^{-1}$) using a new modulated polarization technique. We determine that the functio

The longitudinal and the Hall impedances have been measured as a function of the frequency in a two-dimensional electron gas at low temperatures. The frequency dependence of the longitudinal impedance can be explained in terms of an equivalent parall
