In the present study the results of investigations on polycrystalline MgB2 and on single crystals of YNi2B2C and HoNi2B2C are presented. In particular, measurementes of specific electrical resistance, thermal conductivity, thermoelectric power, and of the linear thermal expansion coefficient were performed. Moreover, the specific heat of polycristalline borocarbide samples was evaluated. From the measured data, the temperature dependencies of the Lorenz number and of the Grueneisen parameter can be determined, also the pressure dependence of the superconducting transition temperature using the Ehrenfest relation. At low temperatures a characteristic deviation of the resistivity from the Bloch-Grueneisen law in the normal state for all inves...
