Mechanical relaxations, spin glasses and 1/f resistance noise
Two experiments related to 1/f resistance noise will be described in this thesis. The first is measurements of the anelastic piezoresistance in thin films of bismuth, niobium and iron to demonstrate a connection between mechanical anelastic relaxations and electrical 1/f noise from the motion of …

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 …

1/F Noise & slow spin dynamics in chromium, chromium alloys, and disordered iron zirconium
1/f resistance noise studies of the spin dynamics in two magnetic systems are described in this thesis. In chromium, 1 If noise was used as a probe to study spin density wave polarization dynamics. Measurements of the noise anisotropy in a high quality single crystal of Cr revealed a temperature …
