Abstract : In the report the authors discuss increases in sound velocity of greater than 60% upon magnetization of highly magnetostrictive Tb(x)Dy(1-x)Fe2, where x approximately equals 0.3. This change corresponds to a Young's modulus increase (delta E Effect) of about 160%, by far the largest known. (Modified author abstract)
