  Ethylammonium nitrate (EAN) and propylammonium nitrate ionic liquids confined
between polar glass plates and exposed to a strong magnetic field demonstrate
gradually slowing diffusivity, a process that can be reversed by removing the
sample from the magnetic field. The process can be described well by the Avrami
equation, which is typical for autocatalytic (particularly, nucleation
controlled) processes. The transition can be stopped by freezing the sample.
Cooling and heating investigations showed differences in the freezing and
melting behavior of the sample depending on whether it had been exposed to the
magnetic field. After exposure to the magnetic field, the sample demonstrated a
change in the state of residual water. Generally, our findings confirm our
previous suggestion that alteration of the dynamic properties of confined
ammonium nitrate ionic liquids exposed to a magnetic field is related to the
alteration of real physical-chemical phases.
