| 摘要 |
The invention concerns a device and a method for generating intense and brief variations of magnetic pressure, predetermined and controlled, capable of being isentropic within a sample (23) of solid material. An electromagnetic cell (1) comprises a flat parallel line of conductive material comprising two branches (4, 5) in the form of planar plates, of similar shapes and dimensions, separated from each other by a distance not more than 3 mm, one of which (4) bears the sample (23) rigidly fixed on said branch (4), said two branches (4, 5) being electrically connected to each other by an end junction strip (7), and to means (2, 3) generating electric current pulses so as to produce in less than 500 ns an electric current flowing in the electromagnetic cell (1).
