Abstract

Recent neutron diffraction and heat capacity measurements revealed that manganese tricyanomethanide, Mn[C(CN)3]2, exhibits an incommensurate spiral magnetic ordering below 1.18 K, consistent with the expectations from the row model for distorted triangular magnets. Here, we present magnetization data measured on a polycrystalline sample at 0.5 K. The saturation field Hsat = 41(1) kOe is determined, in close agreement with the previous estimate from the heat capacity data. The magnetization reaches 5.1(3) μB at 45 kOe, corresponding well to the full high-spin Mn2+ moment. The field dependence of the magnetization exhibits anomalies between 12 and 19 kOe which are related to transitions from the incommensurate spiral to the "up-up-down"-like and the "2-1" spin-flop like magnetic structure observed by neutron diffraction.
