Magnetostriction and Thermal Expansion of Pd and Paramagnetic Pd:Ni Alloys

The magnetostriction of Pd:Ni alloys shows that the volume derivative of the localized exchange enhancement is large and positive in contrast to the corresponding parameter in Pd. The low-temperature thermal expansion has a logarithmic singularity near the critical concentration and shows an anomaly in its temperature dependence like that predicted theoretically.
