摘要：

The spin susceptibility of a polycrystalline sample of uranium mononitride UN is studied by measuring the N-14 NMR line shift, spin-lattice relaxation rates of the nuclear spin, and static magnetic susceptibility in the temperature region of 1.5T(N) < T < 7T(N) A joint analysis of the results obtained has revealed the temperature dependence of the characteristic energy of spin fluctuations of the uranium 5f electrons: (nmr)(T) T-0.54(4) close to the dependence (T) T-0.5 characteristic of concentrated Kondo systems above the coherent state formation temperature.
