2021-9-9  Samples for magnetic susceptibility (MS) were measured in the Geomagnetism Department of the Institute of Geophysics laboratory at the Vietnam Academy of Sciences and Technology, Hanoi. The average distance between samples was 2 cm. All materials are “susceptible” to becoming magnetized in the presence of an external magnetic field.

Magnetic Susceptibility - an overview ScienceDirect Topics

Magnetic susceptibility measurement is an interesting technique for determining phase boundaries in magnetic systems as there is a distinct change in magnetic properties during a phase transition. In this technique the alloy is suspended on a pendulum and a magnetic field is applied. The sample is then heated or cooled through the phase transition and the sample is deflected from its position ...
