Structural and magnetic anomalies among the spin-chain compounds, Ca3Co1+xIr1-xO6
S. Rayaprol, Kausik Sengupta, E. V. Sampathkumaran
The results of x-ray diffraction, and ac and dc magnetization as a function of temperature are reported for a new class of spin-chain oxides, Ca3Co1+xIr1-xO6. While the x= 0.0, 0.3…
