“…Single crystals of CsMgBr 3 doped with Mn 2+ ions (s = 5/2) were studied by EPR measurements at Qand X-band frequencies with the magnetic field parallel and perpendicular to the c axis (McPherson et al, 1974). The EPR spectrum displayed in Fig.…”

Magnetic clusters, i.e., assemblies of a finite number (between two or three and several hundred) of interacting spin centers which are magnetically decoupled from their environment, can be found in many materials ranging from inorganic compounds, magnetic molecules, artificial metal structures formed on surfaces to metalloproteins. The magnetic excitation spectra in them are determined by the nature of the spin centers, the nature of the magnetic interactions, and the particular arrangement of the mutual interaction paths between the spin centers. Small clusters of up to four magnetic ions are ideal model systems to examine the fundamental magnetic interactions which are usually dominated by Heisenberg exchange, but often complemented by anisotropic and/or higher-order interactions. In large magnetic clusters which may potentially deal with a dozen or more spin centers, the possibility of novel many-body quantum states and quantum phenomena are in focus. In this review the necessary theoretical concepts and experimental techniques to study the magnetic cluster excitations and the resulting characteristic magnetic properties are introduced, followed by examples of small clusters demonstrating the enormous amount of detailed physical information which can be retrieved. The current understanding of the excitations and their physical interpretation in the molecular nanomagnets which represent large magnetic clusters is then presented, with an own section devoted to the subclass of the singlemolecule magnets which are distinguished by displaying quantum tunneling of the magnetization. Finally, some quantum many-body states are summarized which evolve in magnetic insulators characterized by built-in or field-induced magnetic clusters. The review concludes addressing future perspectives in the field of magnetic cluster excitations.

“…In CsMgX 3 crystals, the Mg 2+ ion is in the local symmetry D 3d with the threefold symmetry axis coincident with the crystallographic c-axis [1,2]. When Ni 2+ ions are doped into CsMgX 3 crystals, Ni 2+ will replace Mg 2+ ions, and occupy the D 3d site.…”

Taking into account spin-spin (SS), spin-other-orbit (SOO), and orbit-orbit (OO) interactions in addition to general spin-orbit (SO) interactions, the local structures of Ni 2+ in CsMgX 3 (X = Cl, Br, I) are theoretically investigated by using the complete diagonalization method (CDM). On this basis, it is found that the local angles, at the Ni 2+ centres are larger than those, at the hosts. The contributions to the spin-Hamiltonian parameters from spin triplets and slight magnetic interactions are discussed.
