dc.description.abstract <p>In this study, the thermal expansion and Gruneisen parameter of polycrystalline “Pr<sub>5</sub>Ni<sub>2</sub>Si<sub>3</sub>” and “Pr<sub>15</sub>Ni<sub>7</sub>Si<sub>10</sub>” were investigated over the temperature range of 5–300 K. Calculations of the phonon contribution to thermal expansion were made, which allowed the magnetic contribution to thermal expansion to be calculated from the difference between the total thermal expansion and the phonon contribution. This resulted in a temperature-dependent magnetic contribution to thermal expansion that varied with the magnetic ordering of the material. The results show two magnetic transitions in each compound, the higher temperature transition corresponding to the Curie temperature and the lower temperature transition resulting from a spin reorientation.</p>
