Field-tunable magnetic phases in a semiconductor-based two-dimensional Kondo lattice (2008)
Siegert, C, Ghosh, A, Pepper, M, Farrer, I, Ritchie, DA, Anderson, B, ...
We show the existence of intrinsic localized spins in mesoscopic high-mobility GaAs/AlGaAs heterostructures. Non-equilibrium transport spectroscopy reveals a quasi-regular distribution of the spins,...

Sensitivity of the magnetic state of a spin lattice on itinerant electron orbital phase (2008)
Siegert, C, Ghosh, A, Pepper, M, Farrer, I, Ritchie, DA, Anderson, D, ...
Spatially extended localized spins can interact via indirect exchange interaction through Friedel oscillations in the Fermi sea. In arrays of localized spins such interaction can lead to a...
Characterization and petrologic interpretation of olivine-rich basalts at Gusev Crater, Mars (2006)
McSween, Y., Wyatt, M. B., Gellert, R., Bell, J. F., Morris, R. V., Herkenhoff, K. E., ...
Universal conductance fluctuations and scale invariance near the metal-insulator transition (2001)
We present results of measurements of 1/f noise $(10^-3< f
Low frequency noise and non-linear transport in charge-ordered manganites (2001)
Guha, A, Ghosh, A, Raychauhduri, AK
Rare-earth manganites are known to show charge-ordering (CO). The CO state is unstable towards a number of external perturbations including an electric current and shows non linear conductivity. We...
