Abstract

NMRON studies for the \(\left. {| \pm 3} \right\rangle \to \left. {| \pm 2} \right\rangle \) 54Mn transitions in antiferromagnetic MnBr2 \(\cdot \) 4H2O, in the millikelvin regime, are presented and discussed. New values are given for (i) the sum of the effective molecular exchange and magnetic anisotropy fields acting on the Mn2+ ions, \(B_{\text{E}}^{{\text{eff}}} + B_{\text{A}} \)=2.23(2) T, and (ii) the magnetic dipole hyperfine splitting, A=-201.99(1) MHz, electric quadrupole hyperfine splitting P=0.049(8) MHz and pseudoquadrupole splitting \(P\prime \)=1.63(2) MHz for the 54Mn nuclei.
