Abstract

The spontaneous linear magnetostriction at T=0 K in YCo4B is positive along the a axis (λa=1.1×10-3) and negative along the c axis (λc=-2.1×10-3), although the volume magnetostriction below Tc is negligibly small and below the resolution of the x-ray measurement. In CeCo4B, however, both λa and λc are smaller and below about 130 K, a negative volume magnetostriction of the order of 10-3 is observed. An anomalous increase of the resistivity is also found at the same temperature range. This anomalous behavior is assumed to be related with the Ce magnetism in CeCo4B.
