摘要
A method for making a self-assembled spinel having an ordered nanocrystal superlattice. The method may involve the steps of providing an oxide mixture that is capable of forming a spinel having Jahn-Teller ions; sintering or heat-treating the mixture to form the spinel having the Jahn-Teller ions; and cooling the spinel having the Jahn- Teller ions at a rate of less than 400 °C/hour. Also, a nano-scale spinel formed by self- assembly. The nano-scale spinel may include a first phase of spinel comprising a high concentration of Jahn-Teller ions; and a second phase of spinel including a low concentration of Jahn-Teller ions. Further, a high density storage device including a nano-scale spinel formed by self-assembly, the nano-scale spinel including a first phase of spinel comprising a high concentration of Jahn-Teller ions; and a second phase of spinel including a low concentration of Jahn-Teller ions.
