Abstract

The two dimensional magnetism in a triangular lattice of hydroxy Mn- and Fe-mica intercalations has been investigated. The Fe-mica intercalation containing more than 8 wt%Fe shows an XY type ferrimagnetism with the ordering temperature of about 10 K. It is revealed by Mössbauer spectroscopy that only Fe³⁺ is responsible for the ferrimagnetic ordering in the Fe-mica intercalation, although Fe²⁺ ions coexist. The Mn-mica intercalation is most likely a Heisenberg type magnet with a near neighbour antiferromagnetic interaction, and a magnetic ordering is not found at least down to 4.2K. The M(M = Mn, Fe, Co and Ni) dependence of the 2-dimensional magnetic properties of the M-mica intercalations is discussed.
