Specific features of the structure, magnetic properties, and heat capacity of intercalated compounds Cr$_x$TiSe$_2$

Structural features, magnetic properties, and heat capacity of Cr$_x$TiSe$_2$ intercalated compounds with a layered structure have been studied experimentally for 0 $\le x\le$ 0.5. It is shown that, at high chromium concentrations ($x >$ 0.25), the magnetic properties of the compounds are strongly affected by the degree of ordering and distribution pattern of the intercalated atoms. Depending on the cooling rate of samples of the same composition ($x$ = 0.5), an antiferromagnetic or a cluster-glass-type state can be obtained. Heat capacity measurements have revealed a nonmonotonic variation in the lattice rigidity with increasing concentration of intercalated atoms.
