Abstract

Resistivity as a function of the temperature and applied magnetic field was studied in PrCo2B2C intermetallic compound. The resistivity as a function of temperature at different magnetic fields shows a parabolic behavior at low temperatures which persists for magnetic fields up to 7.8 T. Magnetoresistance measurements show negative values at temperatures below 15 K and low fields, and becomes positive at high fields. Specific heat measurements reveal a high value of the Sommerfeld coefficient of about 300 mJ(mol K2)−1. These results at low temperatures are interpreted from the point of view of the spin fluctuations theory.
