Specific heat of FexCo1-xCl2 compounds at low temperatures
Kostryukova M. O.
The specific heat of five Fex Col _ x Cl2 compounds in the concentration range corresponding to values of л: between 0 and 0.7 has been measured between 2 and 27 K. The phase diagram and the spin-wave dispersion laws have been studied in these compounds, for which the initial components are layered antiferromagnets with a strong competing anisotropy.
