| Abstract: | The thermal expansion of U2Fe13.6Si3.4 and Lu2Fe13.6Si3.4 has been measured by X-ray powder diffraction. Both compounds exhibit a large spontaneous magnetostriction. In the ground state, the volume effect 11.2 × 10−3 in U2Fe13.6Si3.4 consists of almost equal contributions from the Fe–Fe and U–Fe exchange interactions (6 × 10−3 and 5 × 10−3, respectively). In Lu2Fe13.6Si3.4, the volume effect is 8.9 × 10−3. |
