1. Device for thermal demagnetization, in particular for rock samples, consisting of: a sample heating chamber, heater, and permalloy screen for suppressing the external magnetic field, characterized in that the heating chamber for samples is a Dewar flask (1) of vertical axis (2), with a heating coil (6) installed inside, and with a removable container (3) for samples (4), whereas the Dewar flask (1) is located inside a thermal insulation (7, 8) with the permalloy screen (9) being the external coat, whereas the heating chamber volume is bigger than 2% of the permalloy screen's most internal volume.<IMAGE>
