Magnetostriction effects in silicone elastomers

IOP Conference Series: Materials Science and Engineering, 2020
Abstract New silicone magnetoactive elastomers have been synthesized and studied. Significant magnetostrictive effects in the synthesized composites were visualized by microscopy. The obtained results can be the basis for the design of controlled dampers and promising magnetostrictive engines of a new generation with micro and nanoscale ...
