The anisotropy of the electrical resistivity and thermal expansion of single crystal DyNi5

The results of the measurements of temperature dependence of the electrical resistivity rho(T), thermal expansion L(T) and susceptibility chi(T) on single crystal DyNi5 in the temperature range 4.2-300 K are reported. The maximum in rho(T) at TN=12.2 K was observed which corresponds to the transition to antiferromagnetically ordered state. Taking into account the Bloch-Grüneisen formula for electron-phonon contribution rhoph(T) to rho(T) the anisotropic magnetic contribution rhomag(T) was determined. We also observed the anisotropic behaviour of L(T) at low temperatures.
