“The specimens were processed using a JR5A spinner magnetometer and demagnetized using a Molspin tumbler demagnetizer.”
“The rocks were then thermally demagnetized with an ASC thermal demagnetizer.”
“They were measured using a Molspin fluxgate magnetometer and subjected to partial thermal demagnetization using a Magnetic Measurements microprocessor-controlled demagnetizer.”
demagnetization
The process of removing the magnetic field from an object.
