Lattice Gas Condensation and its Relation to the Divergence of Virial Expansions in the Powers of Activity

Section: Nanosystems
Original Author's Text:  Ukrainian/English

Abstract: A new technological approach is proposed for the synthesis of multilayered nanostructures,
which provides them unique properties and extraordinary prospects of practical applications. In
particular, the synthesis of the InSe⟨�-��⟨FeSO4⟩⟩ nanostructure with hierarchical architec-
ture in crossed electric and light-wave felds is shown to result in the abnormally strong positive
magnetoresistance efect with giant magnetoresistance oscillations in a low-frequency interval
of 10−3
–10 Hz. The efciency of applying the synthesized nanohybrid as an active element in
gyrator-free delay nanolines controlled by the magnetic feld and in magnetic-feld sensors that
are supersensitive at room temperatures is substantiated.

Key words: InSe, intercalation, clathrate, cavitand, cavitate, hierarchical structures, impe-
dance spectroscopy, magnetoresistive efect.
