| Rock specimens of different ages have different orientations of permanent magnetisation. |
| Isothermal remanent magnetisation parameters were measured in a Molspin flux-gate magnetometer after magnetisation in a Molspin pulse magnetiser. |
| The magnetisation, or the molecular effect, is measured by the deflection of the magnetometer. |
| They measured the temperature and magnetic field dependency of several physical characteristics including resistivity, heat capacity and magnetisation. |
