Spin canting and weak long-range ferromagnetic order in a rigid supramolecular framework

Abstract

In this study we investigated the magnetic properties of the [Mn(ampyz)(AcO)2(H2O)]n compound (1-Mn) (do Nascimento Neto et al., 2019; Lemes et al., 2021). The magnetic properties were studied in a broad range of temperatures 3–400K in magnetic fields up to 60 kOe. The intra and interchain interactions inducing spin canting and long-range ferromagnetic ordering at low temperatures. The coupling constant of J=−1.03cm−1 and zJ=+0.23cm−1 quantitatively indicates the presence of weak antiferromagnetic interactions mediated by ampyz bridging ligand and non-negligible interchain correlations.
