Coupled metal-insulator and magnetic transitions in LnSr(2)Mn(2)O(7) (Ln=La, Tb)
We report magnetisation, conductivity and structural data on the Ruddlesden-Popper MnIII/MnIV oxides LnSr2Mn2O7 (Ln = La, Tb); while LaSr2Mn2O7 undergoes an insulator-metal transition and an increase in spontaneous magnetisation at 132 K, the isostructural terbium compound is semiconducting and para...
