“…The entanglement properties of various cluster magnetic systems were studied in the literature. In the order of increasing cluster size, such systems as: dimers [8,9,10,11,12,13,14,15,16,17,18,19], trimers [20,21,8,22,23,24], tetramers [21,8,25,23,16,26], hexamers [27] or even larger structures [28] of various geometry, including spin wheels [29] of large size and high spin, were investigated, both from the theoretical and experimental point of view. In particular, in the work Ref.…”
