Abstract

Nuclear magnetic resonance measurements have been performed for¹⁸⁹Pt and¹⁹¹Pt oriented at 7 and 15 mk in iron host. The magnetic hyperfine splitting frequencies, ν=|μB_HF/Ih|, of the¹⁸⁹Pt and¹⁹¹Pt ground states were determined to be 277.61(5) and 319.88(3) MHz. With the hyperfine field of B_HF=-1280(26) kG the nuclear magnetic moments were deduced to be: |μ(¹⁸⁹Pt;3/2^-)|=0.427(9) μ^N; |μ(¹⁹¹Pt,3/2^-) |=0.492(10) μ_N. The effective spinlattice relaxation time for¹⁹¹Pt Fe at 7 mK in a polarizing magnetic field of 2 kG has been found to be 30(2) s using a single-exponential fit.
