2G Enterprises 760R-4K Superconducting (SQUID) Rock Magnetometer u-channel System

Specifications:

Magnetometer

• 3-axis SQUID system (measures remanence along x, y, z at the same time).
• Accommodates 1.5 m long u-channels of sediment.
• Or 8 discrete samples at a time (standard paleomagnetic cores, rock cubes, plastic cubes, mounted pieces of material).
• Useable measurement range: 1 x 10^-7 emu to 1 x 10^-2 emu (1 x 10-¹⁰ Am² -- 1 x 10^-5 Am²).

Alternating Field (AF) demagnetizer

• In-line three axis coil system.
• The coils sequentially apply fields along x, y, and z directions in one measurement step as part of a AF demagnetization and remanence measured scheme - there is no need to remove samples during an AF demagnetization run.
• AF range: 1 mT -- 1700 mT
• Includes an additional in-line z-axis DC field coil, allowing anhysteretic remanent magnetization (ARM) to be imparted.
• DC maximum field: 0.1 mT.  

Measurement Types

Typically used for:

• Measuring any form of magnetic remanence
  • Natural Remanent Magnetization (NRM)
  • Anhysteretic Remanent Magnetization (ARM)
  • Isothermal Remanent Magnetization (IRM), which can be imparted by an off-line pulse magnetizer.
  • Thermal Remanent Magentization (TRM), which can be imparted using a thermal demagnetizer with integrated DC coils.
• Running programmed automated AF demagnetization sequences for determining paleomagnetic directions and magnetic coercivity spectra.
• Rock magnetic measurements. Measurement of ARM and IRM can aid in understanding magnetic mineralogy and is useful, e.g., in environmental studies.
• Measurements of NRM and TRM for paleointensity experiments.
• Anisotropy of ARM (AARM) and TRM (ATRM) measurements.
