Resistance fluctuation spectroscopy and other transport behavior in lanthanum barium copper oxide
… striped phase is expected to include local resistance anisotropy, this has not been observed, and LBCO’s stripe behavior has only been studied by scattering experiments at beamline facilities. In this work, pulsed-laser deposition and microfabrication were used to create small- volume LBCO …

Mesoscopic noise probe of an inhomogeneous colossal magnetoresistance phase
… 3Ca1; 3Mn03 exhibit large discrete equilibrium resistance fluctuations in the region of phase space where colossal magnetoresistance effects are strongest. The fluctuators' dependence on magnetic field indicates that the resistance steps represent small regions of material fluctuating between a …

Low Frequency Noise in Semiconductors and Metals (Statistics, Gaussian (Noise)
Properties of l/f noise (low frequency resistance fluctuations) are analyzed using the results of a number of experiments, several of which are unique to our laboratory. Measurements of thermally activated noise spectral features, as well as the effect of a surface potential of the noise kinetics …

1/f noise in semiconductors and metals
Properties of 1/f noise (low frequency resistance fluctuations) are analyzed using the results of a number of experiments, several of which are unique to our laboratory. Measurements of thermally activated noise spectral features, as well as the effect of a surface potential on the noise kinetics …

Electrical noise in the spin-glass AuFe
Measurements of electrical resistance fluctuations have been performed on the spin-glass AuFe in order to compare with prior results in CuMn. Macroscopic AuFe samples showed a sharp increase in the noise with the onset of the noise at a temperature corresponding to the peak in the magnetic …

Percolation and nanosecond fluctuators in V2O3 films within the metal-insulator transition
… in bias current, as expected for resistive fluctuations probed nonperturbatively by the current. The low frequency noise generally resembles flicker-type 1/f^α noise, often taking on the form of Lorentzian noise dominated by a small number of fluctuators as the volume fraction of the …

Hydrogen concentration and temperature affect the 1/f resistance noise in niobium films
"The 1/f resistance fluctuations of thin Nb films was studied from 60 K to 400 K. The resistance noise came from hydrogen ions and other defects placed in the films during sputtering. Hydrogen ions cause three types of 1/f noise at different temperatures. The noise is related to internal friction …
