Abstract
Abstract The electrical resistivity and magnetoresistance of the weak itinerant-electron ZrZn2 were measured. The resistivity varies with temperature as T2 below the Curie temperature Tc with a large coefficient 4.7 × 10 -8 Ω cm K -2 and changes its slope very slightly at Tc. A negative magnetoresistance was observed above about 10 K. It shows a maximum at Tc. This behaviour is suggested as characteristic of weak itinerant-electron ferromagnets.
