Phonon effects on magnetosensors

This article gives a good overview of the role of phonons in magnetosensor research.

"The notion is that if you have higher temperature applications, most materials' response to magnetic fields [the magnetoresistive response] falls off very rapidly because of excitations of the lattice--phonon vibrations," explained University of Chicago professor Thomas Rosenbaum. "But it turns out the mechanism we are adapting to [indium antimonide] is not limited by the phonons."
