Structure and properties of novel cobaltates Ln0.3CoO2 (Ln = La, Pr, and Nd)
Original language description
Layered cobaltates LnxCoO2 (Ln=La, Pr, Nd; x 0.30), isostructural with well known thermoelectrics NaxCoO2, have been characterized by diffraction methods and probed by the electric transport, magnetic and heat capacity measurements. The thermopower increases with temperature and saturates above room temperature at a large value 175 lV=K. The conductivity is affected by occupational disorder and follows Mott?s T-1/n law. The main attention is given to Pr0.3CoO2 and Nd0.3CoO2, in which the spins of hole carriers in the CoO2 layers coexist with localized magnetic moments of Pr3+ or Nd3+. The systems are found paramagnetic down to the lowest temperatures and behave accordingly to the non-Kramers or Kramers character of the rare earth ions.
