11- 16 Therefore, systematic studies on a series of compounds from a given family are essential. The reasons behind the significant difference in T B 100s, despite having comparable energy barriers, can be attributed to the differences in the other relaxation processes involved, for example, Raman and quantum tunnelling of magnetization (QTM), and therefore it is necessary to understand these mechanisms in detail to design higher-performing SMMs. 6, 7- 10 Two of the recent high-performing SMMs, ( 4) 6a and ( 5, Cp ttt, C 5H 2 tBu 3-1,2,4) 7 have similar Δ values (1815 K and 1760 K, respectively) but very different T B 100s (12 K in 4 and 53 K in 5 here we use T B 100s to define the temperature at which the magnetic relaxation time is 100 s in zero field).

3, 4 The design criteria to synthesise Ln SMMs, 5 with a single Dy III centre in a highly axial ligand field environment to generate large magnetic anisotropy and to stabilise the highest m J=☑5/2 spin state of Dy III as the ground state, has led to Ln SMMs with magnetisation dynamics dominated by an Orbach-like (thermally activated) relaxation process, with very high values of the activation energy (Δ). Lanthanide (Ln) SMMs have provided some promising candidates since their discovery in 2003. 1, 2 For technological applications, it is important to determine the highest temperature at which a SMM can retain its magnetisation, 1 and to understand the multiple relaxation mechanisms, which can be involved in their magnetic dynamics.

Single-molecule magnets (SMMs) show slow relaxation of magnetisation under certain conditions these have received huge interest in the last 25 years due to their potential applications in quantum computing, molecular spintronics and ultra-high-density storage.
