Abstract The semi-quantum two-orbital exchange model is used to investigate the effect of small rare-earth ion substitution on orthorhombic RMnO3 with A-type antiferromagnetic order, using the Monte Carlo algorithm, exact diagonalization, and zero-temperature optimization approaches. It is revealed that the substitution results in a rich multiferroic phase diagram where the coexisting A-type antiferromagnetic phase and spiral spin phase, pure spiral spin phase, coexisting spiral spin phase, the E-type antiferromagnetic phase, and the pure E-type antiferromagnetic phase emerge in sequence. The multiferroic phase transitions modulate substantially the electric polarization, which is consistent qualitatively with recent experiments.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
