Claims

C1strongest claim

These results, coupled with pressure-tuned DFT calculations, confirm the prior prediction that the primary exchange interaction is mediated via an unusual mechanism in which the V(IV) ions provide considerable spin density to the oxygen that joins the two spins in each dimer and which lies along the Jahn-Teller axis of the Cu(II) ion.

C2weakest assumption

That the DFT calculations correctly capture the pressure-induced structural distortions and resulting spin-density distribution without significant functional or parameter choices that could alter the identified mediation path.

C3one line summary

Pressure-dependent experiments on a heterometallic Cu-V spin-1/2 dimer magnet confirm an unusual exchange mechanism mediated by vanadium spin density on the linking oxygen along the Cu Jahn-Teller axis.
