Magnetic Anisotropy and Mechanism of Magnetic Relaxation in Er(III) Single-Ion Magnets

Inorganic Chemistry, 2014
Magnetic anisotropy is a key component in the design of single-molecule magnets (SMMs) possessing a large barrier height for magnetization reversal. Lanthanide-based SMMs are the most promising candidates in this arena as they offer a large magnetic anisotropy due to the presence of strong spin-orbit coupling.

The magnetic single-ion anisotropy in hematite

Chinese Physics Letters, 1987
A calculation of the magnetic single-ion anisotropy in hematite has been made. The results show that an equivalent single-ion anisotropy field Hsi (=103.8×102 Oe) exists along the c-axis at T=0K. The Morin transition in hematite could be explained by our results in conjunction with the calculated Hmd by Artman et al.

Single-ion magnetic anisotropy theory in amorphous magnetic alloys

Journal of Magnetism and Magnetic Materials, 1990
Abstract The magnetic anisotropy of amorphous magnetic alloys is investigated in the framework of the single-ion theory, which was previously formulated for the crystalline case only. It is found that the anisotropy of the atomic distribution determines the magnetic anisotropy constants.

Slow Magnetic Relaxation in Dysprosium Based Single-Ion Magnets

2016
The experimental and theoretical study of two mononuclear dysprosium-based complexes is reported. Both complexes demonstrate slow relaxation of magnetization at low temperatures. The Hamiltonian for explanation of the magnetic behavior (the magnetic susceptibility as a function of temperature and magnetization as a function of the applied magnetic ...

Three Dy(iii) single-ion magnets bearing the tropolone ligand: structure, magnetic properties and theoretical elucidation.

Dalton Transactions, 2019
The reactions of dysprosium nitrate with the main ligand of tropolone (HL) in the presence of ancillary ligands of phenanthroline (phen) or 1,3,5-benzenetricarboxylic acid (H3BTC) gave three mononuclear complexes, [Dy(phen)2(L)(NO3)2] (1), [Dy(phen)(L)3]·

Single-Ion Magnetic Interactions in Diamagnetic Spinels

Journal of Applied Physics, 1969
The continuing interest in the magnetic properties of the spinel structure has prompted us to explore in detail the single-ion interactions of magnetic ions in diamagnetic spinel host crystals. In particular we report ESR and optical absorption measurements on Cr3+ and Fe3+ ions in crystals of ZnGa2O4 and ZnAl2O4.
