Description
A polycrystalline sample of the Mn(III) complex K3[Mn(CN)6] was measured on the cold neutron time-of-flight spectrometer Pelican at ACNS in October 2020, under a range of applied magnetic fields of 0 ≤ B ≤ 7 T. The spectra obtained in zero-field clearly show a pair of magnetic excitations centered at ca. 9.5 meV, in accord with previous measurements on IN4 at ILL and MARS at PSI. In externally applied magnetic fields, these excitations were found to be significantly modified, consistent with a Zeeman split pair of spin doublets that move apart as a function of field. This behaviour is believed to be the result of crystal field and Jahn-teller distortions of the octahedral Mn centre.
