Our news journalists obtained a quote from the research, "The increase of the dichroism with increasing concentration in diluted samples (0.21%) is mainly caused by the pair correlations in the first coordination layer, predominantly along the magnetic field direction. In the 1-3% concentration range, the first coordination layer becomes increasingly isotropic while pair correlations in the second coordination layer grow transversally to the magnetic field direction. Thus, with the increase of the concentration above 2%, the dichroism decreases as a combined effect of the changes in the symmetry of the pair correlations in the first and the second coordination layers."
According to the news editors, the research concluded: "The proposed dichroism model predicts the possibility of negative magnetically induced dichroism in highly concentrated perfect colloidal dispersions of small spherical magnetic nanoparticles."
