Electron paramagnetic resonance and thermodynamics of Langmuir—Blodgett films of manganese arachidate and of its mixtures with Methyl arachidate (cas 1120-28-1)

The Langmuir—Blodgett technique has been used for the preparation of magnetic multilayer films of manganese arachidate either as a pure component or in mixture with the diamagnetic methyl arachidate. The mutual surface miscibility of both compounds was verified from the spreading isotherms of their mixtures. The spreading isotherms allowed us to find the optimum conditions for the transfer of monolayers onto silanized quartz plates and to prepare LB films with more than 100 layers.Electron paramagnetic resonance spectroscopy has been used to characterize the magnetic properties of the films. The typical shape anisotropy of quasi-two-dimensional magnets was observed from the orientation dependence in the magnetic field of the linewidth and from the changes of both linewidth and resonance position with temperature at T < 15 K. This behavior occurred for methyl arachidate/arachidic acid (MeAr/ArAc) molar ratios <5. At ratios >5 the usual isotropic properties were observed.
