At the first time, by the results of complex structural, thermodynamic, magnetic studies and theoretical modeling it was proved that cobalt-containing
layered double hydroxyls (Co2+nAl3+) (n = 2, 3) with anions and water molecules intercalated between the layers are two-dimensional magnetics, which low-temperature
magnetic behavior s determined by the cleavage and settlement of the lowest Co2+ doublets, which, in turn, depend on possible distortions of the surrounding hydroxyl
octahedra. The material is considered promising for the design of complex artificial structures and nanocomposites.

A new phenomenon has been discovered and scientifically described - the existence of dichroism in the basal plane
in the easy axis magnetic state of the antiferromagnet HoFe3(BO3)4, which changes its sign when
the direction of the external magnetic field is reversed. The detected effects are associated with a violation of the
axial symmetry of the spiral structure of the magnetic moments of holmium in excited states.
Rare-earth ferroborates have great prospects for modern technological applications due to their non-trivial
magnetic properties and pronounced multiferroic effects.
