Anomalous magnetic exchange in a dimerized quantum magnet composed of unlike spin species

We present here a study of the magnetic properties of the antiferromagnetic dimer material CuVOF4(H2O)6 · H2O, in which the dimer unit is composed of two different S = 1/2 species, Cu(II) and V(IV). An applied magnetic field of μ0Hc1 = 13.1(1) T is found to close the singlet-triplet energy gap, the...
