Thermal expansion and NMR of CePdSb

The thermal expansion coefficient of polycrystalline CePdSb shows no feature at the Curie point (17 K) but a broad peak near 10 K, in agreement with earlier measurements of the magnetic heat capacity. Single-crystal measurements show that the thermal expansion coefficient of the magnetically hard c direction is an order of magnitude greater than that of the a or b direction. The temperature dependence of the zero external field Sb NMR does not show any unusual behaviour near 10 K.
