Dependence of magnetic exchange on superstructure in sodium cobaltate

We are able to grow large single crystals of Na0.8CoO2 and to control the sodium superstructure via the cooling rate. Quenching rapidly to low temperature gives a striped phase,...我们可生长出Na₀.₈CoO₂大尺寸单晶，并可通过冷却速率调控其钠超结构（sodium superstructure）。快速淬冷至低温即可得到条纹相（striped phase）……
