Fig. 2: Zeeman diagram of the ground ferromagnetic state of Tb2Pc3.
From: Increasing the Hilbert space dimension using a single coupled molecular spin
a Tb2Pc3 Zeeman diagram, considering all interactions. The ten colours are associated with the sixteen coupled nuclear spin states. Note that some of the events are degenerated. b Enlargement highlighting the ten anti-crossings, where the electronic spins reverse simultaneously. For each of the ten anti-crossings, the electronic spins have a Landau–Zener probability P to reverse from a \({|}\!+\!6,+6\rangle\) state to a \({|}\!-\!6,-6,\rangle\) state. c Enlargement of one of the anti-crossings, with an anti-crossing energy ∆.
