THERMAL-EXPANSION AND NMR OF CEPDSB

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