The magnetic properties of Cu c Co 1-c Cl 2-FeCl 3 GBICs have been studied using DC and AC magnetic susceptibility measurements.
The Curie-Weiss temperature is positive for all concentration AC magnetic susceptibility shows two broad peaks at T cu and T cl due to the spin orderings in the Cu c Co 1-c Cl 2 layers and the FeCl 3 layers, respectively. These spin orderings are coupled to Cited by: 1.

Graphite intercalation compounds (GICs) have high electrical conductivities, large Seebeck coefficients, and low thermal conductivities as compared with their host graphite materials.
Due to these properties, GICs are expected to act as effective thermoelectric by: Abstract. This paper will provide a current review of the electrical conductivity of the donor and acceptor intercalation compounds of graphite based on the research of the group at Penn and their by: 5.

Magnetic measurements can be extended to study magnetic structure and electronic properties of materials used in lithium power sources, i.e., the so-called lithium intercalation compounds (LiICs).

Because carbon occupies a middle position in the order of electronegativity of the elements in the periodic table, graphite welcomes many chemicals as guests, or intercalants, making it possible to produce Cited by: Graphite intercalation compounds are a new class of electronic materials that are classified as graphite-based host guest systems.
They have specific structural features based on the alternating stacking of graphite and guest intercalate sheets. The electronic structures show two-dimensional metallic properties with a large variety of features including superconductivity. Among a variety of graphene-based materials, graphene intercalation materials are formed by insertion of molecular or atomic layers with various chemical species between graphite layers.
4,[ Solid‐state physicists are turning more and more to complex synthetic materials in their search for novel phenomena and potentially useful properties. Many of these materials are highly anisotropic, so that interatomic interactions can for all practical purposes be neglected along one or two crystal axes.
