Dimim[FeCl4]: A magnetic ionic liquids with unclear magnetic behavior
Dimim[FeCl4] is a magnetic ionic liquid. A complete picture of its magnetic behavior is still missing being extremely sensitive to temperature cooling rate effect. Therefore, using suitable rates of cooling from room temperature solid state, two ordered crystalline phases can be obtained with different magnetic behaviours. One of them display an antiferromagnetic structure whereas the other one exhibits a magnetic phenomena. Therefore, the competition between interactions are modified by this effect being the study of the magneto-structural correlations the major goal of this research. For this objective, we consider that a combination of low angle and polarized neutron diffraction are needed. To accomplish this proposal we apply to 7 and 2 days of beam time at D7 and D33, respectively. Having the experimental knowledge of this magnetic phenomena will allow a direct connection to theoretical models.
