Gated two-dimensional electron gas in magnetic field: Nonlinear versus linear regime

Ennn, l'amélioration de certains services d'intérêt général par l'utilisation de technologies de l'infor- mation et de la communication peut être analysée comme un

If the magnetic mode amplitudes are reduced, being for instance reduced to the fourth of the case just con- sidered in Figure 4, this differential heating is strongly attenuated as

at various temperatures and external magnetic fields have been obtained to study the influence of the external field on the anomalous behaviour of < S z > , and to

It is concluded that the quantum spin fcc lattice with nearest neighbour anti- ferromagnetic Heisenberg and dipolar interactions ex- hibits several distinct multi-k ground

Spin waves may be found in a multiple layered elec- tron gas (LEG) if either the system is ferromagnetic, or if it is even non-magnetic but placed in a strong

We have studied the propagation of highest energy cosmic rays in the Galactic magnetic field, for different assumptions on the large-scale field structure and/or primary cosmic ray

These results are extended in order to take into account strong- coupling effects and we show how measurements under a magnetic field may provide information
