Research
Facility
The
Paleomagnetism Laboratory, otherwise known as the chalet,
was completed in 1985 and is located on the UC Santa Cruz
campus in a remote building specially constructed with non-magnetic
materials and isolated from major sources of man-made magnetic
noise. Inside this building, a magnetically shielded room
houses a state-of-the-art superconducting magnetometer,
a sensitive spinner magnetometer, thermal and alternating
field demagnetizaters, and paleointensity equipment. A second
lab devoted to the study of rock and mineral magnetic properties
is housed in the Earth and Marine Sciences Building. It
contains another spinner magnetometer, devices for measuring
Curie temperatures, magnetic susceptibility and its anisotropy,
hysteresis loops, and computer facilities for data analysis
and graphics.
