The recent discovery of relaxor ferroelectricity and magnetoelectric effect in lightly doped cuprate material La2CuO4+x has provided a number of questions concerning its theoretical description. Using a Ginzburg–Landau free energy approach, it has been argued that the magnetoelectric effect can be e...
