Abstract:
Ñointerñalated materials are studied, obtained by introducing copper into a TiSe$_2$ lattice preintercalated with transition metals $M$ = Mn, Fe, Co, or Ni. The analysis of the state of cointercalated systems at 950$^\circ$C shows that copper reduces manganese and iron, but it is incapable of reducing cobalt or nickel. To explain the results, the values of the binding energy of hybrid states $M$3$d$/Ti3$d$ are compared.
