On magnetic transitions in a novel compound, UPdGa

Abstract

A new ternary uranium compound, UPdGa, crystallizing in the hexagonal Fe₂P-type structure has been prepared. The magnetic and electrical properties of this material have been studied in the temperature range 4.2–300 K. The results obtained indicate the appearance of two magnetic phase transitions at 30 and 62 K, probably originating from an antiferromagnetic ordering.
