Abstract
An instrument for measuring giant magnetostriction of rare-earth metal s is described. Owing to the optoelectronic cell with a linear charact eristic, this device makes it possible to measure small-sized (8-10 mm ) samples cooled to 78 K. The accuracy of sample length measurements i s 0.05 mu m, and the time required to measure the magnetostriction hys teresis loop is 1 min. Magnetostriction of dysprosium and terbium were measured with this device.
