Equipment

 

Lund University Palaeomagnetic and Mineral Magnetic Laboratory is well equipped to measure natural and artificially induced magnetizations. The "flagship" of the laboratory is a 2G-Enterprises superconducting rock magnetometer (model 755-R), which has automatic alternating field demagnetization coils (max. 250 mT) with an inbuilt direct current coil for producing anhysteretic remanent magnetizations (ARM’s).

Thermal demagnetization of samples can be undertaken in a Magnetic Measurements Ltd MMTD80 thermal demagnetizer, which is equipped with a solenoid and constant current power supply for producing thermal remanent magnetization (TRM's) as part of the Thellier-Thellier palaeointensity method. Heating can take place in a controlled inert atmosphere.

Other equipment includes:
1. An in-house built magnetic susceptibility core conveyor coupled to a Bartington Instruments Ltd MS2 meter and MS2E1 surface scanner. Discrete sample MS2B dual frequency sensor and a whole core loop are also available.
2. Geofyzica Brno KLY-2 Kappa bridge with the CS-2 facility for measuring the temperature dependence of magnetic susceptibility.
3. A Redcliffe 700-BSM pulse magnetizer and two Molspin Minispin magnetometers for the induction and measurement of isothermal remanent magnetizations.
