要旨:
Measurements of electrical resistivity and Hall effect as a function of
magnetic field on the heavy fermion systems YbNiAl and YbPtAl are
presented. Both compounds order antiferromagnetically and show
metamagnetic behavior in a magnetic field. Scaling behavior of the
magnetoresistance above T N suggests that the paramagnetic regime for
YbNiAl can be described in terms of a single ion Kondo effect.
