Aurivillius phases (type 1) should be very similar electronically to copper–oxide superconductors when the transition metal M in 1 has a d l or d 3 configuration instead of a d o configuration. Such materials might exhibit superconductivity. This result, obtained by calculation, should stimulate further experiments in the area of oxidic high‐ T c superconductors.
