The macroscopic magnetic characterization of the Mn(II) - nitronyl nitroxidefree radical chain (Mn(hfac)2(R)-3MLNN) evidenced its transition from a1-dimensional behavior of ferrimagnetic chains to a 3-dimensional ferromagneticlong range order below 3 K. Neutron diffraction experiments, performed on asingle crystal around the transition temperature, led to a different conclusion: the magnetic Bragg reflections detected below 3 K correspond to a cantedantiferromagnet where the magnetic moments are mainly oriented along the chainaxis. Surprisingly in the context of other compounds in this family of magnets,the interchain coupling is antiferromagnetic. This state is shown to be veryfragile since a ferromagnetic interchain arrangement is recovered in a weakmagnetic field. This peculiar behavior might be explained by the competitionbetween dipolar interaction, shown to be responsible for the antiferromagneticlong range order below 3 K, and exchange interaction, the balance between theseinteractions being driven by the strong intrachain spin correlations. Moregenerally, this study underlines the need, in this kind of molecular compounds,to go beyond macroscopic magnetization measurements.Comment: 12 pages, 10 figures, submitted to Phys. Rev.
