Neutron thermometry applied to magnetization and spin-lattice relaxation measurements on silver nuclei
We have studied spin-lattice relaxation in silver metal at temperatures and magnetic fields beyond the validity of the normal Korringa relation τ 1 = κ/T c using transmission of polarized and unpolarized neutrons. For the Korringa constant of 109Ag we obtained κ = (10.0± 0.3) sK.
Unpolarized neutrons were also used to measure the critical value of entropy S for nuclear antiferromagnetic ordering and to determine the induced magnetization M in the ordered state. The nuclear susceptibility X = μ 0 M/B = 0.36 ± 0.01 was found to be constant, independent of S and B (B c ≈ 100 μT).
