Intermediate valence to single ion Kondo behaviour in CePd3Bx alloys

Susceptibility, resistivity thermopower and magnetoresistivity data are presented for CePd(3)B(x) alloys, where the boron enters the lattice interstitially. All the data are consistent with a smooth cross-over from intermediate valence in CePd(3) to trivalent local moment behaviour in CePd(3)B(0.3). For x < 0.15 the alloys mirror the properties of CeP(3), but on reduced temperature scales. For 0.15 less than or equal to x < 0.3 the alloys obey single impurity Kondo theory, while the x = 0.3 alloy is close to the localised limit.
