# Giant Spin-Electric Coupling in Heterometallic Porphyrin Dimers

Lu et al., 2026, Physical Review Letters — Chemistry

Patterns: [Distinctions](https://dsrpevidence.org/pattern/distinctions), [Relationships](https://dsrpevidence.org/pattern/relationships)

## In short

The giant magnetoelectric effect is a relationship (electric field controlling spin coupling) that exists only because the two metal centers in the dimer are categorically distinct, so the effect reported is inseparable from that distinction.

## What they found (results)

Heterometallic porphyrin dimers show spin-electric coupling coefficients one to four orders of magnitude larger than conventional 2D magnetic systems, letting practical electric fields switch the molecule between ferromagnetic and antiferromagnetic coupling states.

These researchers were not testing DSRP. The finding is theirs; the correspondence to DSRP is drawn by this site.
