“…Magnetometry in alternating current magnetic fields ( ac ‐magnetometry) is the most popular method in SMM research, which directly accesses the magnetization relaxation time; other techniques of choice are dc‐magnetometry,, far‐infrared spectroscopy, magnetic circular dichroism, NMR spectroscopy, and electron paramagnetic resonance (EPR) spectroscopy ,. The latter is rarely used for studying SMMs.…”

“…Magnetometry in alternating current magnetic fields (acmagnetometry) is the most popular method in SMM research, which directly accesses the magnetization relaxation time; other techniques of choice are dc-magnetometry, [8,9] far-infrared spectroscopy, [11] magnetic circular dichroism, [12] NMR spectroscopy, [13][14][15][16][17][18][19][20] and electron paramagnetic resonance (EPR) spectroscopy. [21,22] The latter is rarely used for studying SMMs. At conventional frequencies, they are almost always EPR-silent, as the transition M S = À S↔ + S is forbidden by the selection rules for large S, and high-lying M S = � 1/2 Kramer's doublet is unpopulated.…”

A Trigonal Prismatic Cobalt(II) Complex as a Single Molecule Magnet with a Reduced Contribution from Quantum Tunneling

Herein, we report a new trigonal prismatic cobalt(II) complex that behaves as a single molecule magnet. The obtained zero‐field splitting, which is also directly accessed by THz‐EPR spectroscopy (−102.5 cm−1), results in a large magnetization reversal barrier U of 205 cm−1. Its effective value, however, is much lower (101 cm−1), even though there is practically no contribution from quantum tunneling to magnetization relaxation.

“…At present, dedicated instrumentation is accessible only to few laboratories worldwide whist the implementation of two-qubit gates with molecular spin ensembles would require more flexibility/tunability on both molecular qubits and instrumentation. Moreover, in spite of the progress achieved in using pulsed ESR techniques to molecular electron spins [34], much work still remains to be done to encompass heterogeneities of both molecular features and applied field and, more in general, to efficiently decouple spin to the environment. For instance, very interesting results have been obtained in the optimization of pulse sequences for dynamical decoupling [35].…”

“…It is notable that luminescence spectra under varying external magnetic fields present the positions of the sublevels of the ground term, while this energy splitting may be difficult to obtain via the electron paramagnetic resonance technology, since the large ligand field splitting of Ln ions challenges the faculties of EPR in high frequency and high magnetic field. 47 …”
