Laboratory Details

Laboratorio de Magnetismo de Materiales y Magnetismo Ambiental (L-MAGMA)

The Laboratory of Materials Magnetism and Environmental Magnetism (L-MAGMA, Laboratorio de Magnetismo de Materiales y Magnetismo Ambiental) of Instituto Geográfico Nacional (IGN) is focused on environmental magnetism and rock magnetism analysis and research. It began operating in January 2020 with the acquisition and commissioning of an MS3-Bartington system for measuring magnetic susceptibility. Since then, L-MAGMA has continuously expanded its instrumentation and facilities. Nowadays, L-MAGMA instrumentation allows the measurement of: magnetic susceptibility in standard discrete samples (at two frequencies), very small samples (< 1 ml), whole sedimentary and rock cores, flat rock and sedimentary surfaces at 5 mm resolution (half-cores), outcrops and terrain in the field; Isothermal Remanent Magnetization (IRM) acquisition and back demagnetization curves; Natural Remanent Magnetization (NRM) analysis by Alternating Field (AF) demagnetization; Anhysteretic Remanent Magnetization (ARM); temperature dependence
