Magnetic properties and magnetic ordering in the Rare Earth Molybdenum(IV) Pyrochlores: R2Mo2O7

Abstract The series of cubic pyrochlore structure compounds, R 2 Mo 2 O 7 (R = Nd—Yb, Y; R ≠ Eu), were prepared as single phase materials by solid state reaction between R 2 O 3 and MoO 2 at 1400°C in a CO/CO 2 = 1 buffer gas atmosphere. Lattice constants obtained from X‐ray powder data compare well with results from previous studies. Magnetic susceptibility and magnetization data were obtained for all samples between 300 K and 4.2 K (700 K …
