TLDR
In this paper, the authors present an explanation for the origin of the diamagnetic correction factors, organized tables of constants compiled from many sources, a simple method for estimating the correct order of magnitude for the diamagnetism correction for any given compound, and a clear explanation of how to use the tabulated constants to calculate the magnetic susceptibility.Abstract:
Measured magnetic susceptibilities of paramagnetic substances must typically be corrected for their underlying diamagnetism. This correction is often accomplished by using tabulated values for the diamagnetism of atoms, ions, or whole molecules. These tabulated values can be problematic since many sources contain incomplete and conflicting data. This article presents an explanation for the origin of the diamagnetic correction factors, organized tables of constants compiled from many sources, a simple method for estimating the correct order of magnitude for the diamagnetic correction for any given compound, a clear explanation of how to use the tabulated constants to calculate the diamagnetic susceptibility, and a worked example for the magnetic susceptibility of copper acetate.read more

Magnetic hysteresis up to 80 kelvin in a dysprosium metallocene single-molecule magnet
Fu-Sheng Guo,Benjamin M. Day,Benjamin M. Day,Yan-Cong Chen,Ming-Liang Tong,Akseli Mansikkamäki,Richard A. Layfield +6 more
TL;DR: A dysprosium compound is reported that manifests magnetic hysteresis at temperatures up to 80 kelvin, which overcomes an essential barrier toward the development of nanomagnet devices that function at practical temperatures.

Slow magnetization dynamics in a series of two-coordinate iron(II) complexes
Joseph M. Zadrozny,Mihail Atanasov,Mihail Atanasov,Aimee M. Bryan,Chun Yi Lin,Brian D. Rekken,Philip P. Power,Frank Neese,Jeffrey R. Long +8 more
TL;DR: In this paper, a series of two-coordinate complexes of iron(II) were prepared and studied for single-molecule magnet behavior, and the spin reversal barriers were fit by employing a sum of tunneling, direct, Raman and Orbach relaxation processes, resulting in spin reversal barrier of Ueff = 181, 146, 109, 104, and 43 cm−1 for 1−5, respectively.

Katie R. Meihaus,Jeffrey R. Long +1 more
TL;DR: Results highlight the utility of an equatorial ligand field for facilitating slow magnetic relaxation in the prolate Er(III) ion and the highest blocking temperature yet observed for a mononuclear complex and the second highest for any single-molecule magnet.
