Abstract
Investigations on the magnetic properties of actinide element intermetallic compounds has disclosed that UGe 2 and PuGe 2 are ferromagnetic with magnetic moments greater than 0.803 and 0.144 Bohr magnetonper molecule respectively at 4°K. Electrical resistivity measurements on UGe 2 indicate an interaction of theconduction electrons with the local spin which produces ferromagnetism. Also the electrical resistivity of USi 2 , which is not ferromagnetic, was measured for comparison.
