Resumen
The present invention provides a positioning device that has a high mechanical stability so it can be incorporated in a local probe microscope, being operable in cryogenic environments, especially at low temperatures, at very low temperatures, and at temperatures less than 100 mk, and additionally in the presence of high magnetic fields. The device comprises a solidary base of the local probe microscope, a sample holder, a guiding means between the base and the sample holder and an actuator located outside the low temperature enclosure. Thermally insulating force transmitting means transmit the impulse from the actuator to the sample holder. The friction between the base and the sample holder is minimized to the maximum.
