Quantum dynamics in molecular nanomagnets

New salen-type dysprosium(III) double-decker and triple-decker complexes

“…Owing to the fact that their size is at the molecule level, SMMs represent good candidates for observations of various physical phenomena and form the basis of many potential scientific applications, such as quantum computing [1][2][3][4][5][6][7] and spintronics [8][9][10][11][12]. Although research on SMMs started in the early 1990's [13,14], lanthanide containing SMMs were not discovered until 2003 [15][16][17][18][19][20].…”

First-principles study of an iron-based molecule grafted on graphene

“…More recently, surface-enhanced Raman signal has been realized on pyrene-based molecules grafted on graphene 16,17 , allowing a detection down to the limit of few isolated molecules. Detection of single molecule magnet [17][18][19] by using graphene or carbon nanotubes could also be a way to probe magnetic properties at the single molecule level. Theoretically, ab initio calculations on magnetic properties of graphene based materials have been performed 11,12 .…”

Solvent Responsive Magnetic Dynamics of a Dinuclear Dysprosium Single‐Molecule Magnet

“…Therefore the magnetic interactions between the dimers could be enhanced in compound 2. [35] However, compared with that in 1, the QTM effect is much less efficient in compound 2. The hysteresis loops were recorded for the powder samples of compounds 1 and 2 using a SQUID-VSM instrument at a sweeping rate of 700 Oe s À1 (Figure 7).…”

“…Such behavior confirms the presence of QTM that the tunneling can be diminished by increasing the field sweeping rate. [35] However, compared with that in 1, the QTM effect is much less efficient in compound 2. Magnetic studies of the rehydrated sample (1-re) reveal that it shows SMM behavior identical to that of compound 1 (Figures S25 and S26 in the Supporting Information).…”
