Complex oxide

[1] Complex oxide materials are notable for their wide range of magnetic and electronic properties, such as ferromagnetism, ferroelectricity, and high-temperature superconductivity.

Magnets made of the complex oxide ferrite are commonly used in transformer cores and in inductors.

Piezoelectric transducers and actuators are often made of the complex oxide PZT (lead zirconate titanate).

As of 2015, there is research underway to commercialize complex oxides in new kinds of electronic devices, such as ReRAM, FeRAM, and memristors.

Another potential application of complex oxide materials is superconducting power lines.
