“…Single-ion magnets (SIMs) are simply a subclass of SMMs wherein the electronic spin term originates from a single magnetic centre [7,8]. In SIMs, the ion bearing the spin is most commonly a transition metal [9][10][11][12][13], lanthanoid [14][15][16][17][18][19][20][21][22], or actinoid [23][24][25][26][27][28][29][30]. The term SIM is somewhat of a misnomer: all SIMs are molecular in nature since the ligand field is a vital prerequisite for their slow relaxation.…”

Over the past fifteen years or so, the study of f-element single-ion magnets (f-SIMs) has gone from being a sub-discipline of molecular magnetism to an established field of research in its own right. The major driving force has been their exceptional promise in applications such as ultra-high-density data storage, spintronics, and quantum information processing (QIP). Recent demonstrations that f-SIMs preserve their intrinsic magnetic properties even when deposited onto substrates have reinforced the interests in the field.Here, we review the current state of the field of lanthanide and actinide f-SIMs; discuss the principal factors affecting the magnetic and quantum properties of such single-ion magnets; review the latest chemical approaches in designing f-SIMs with superior properties; and highlight new trends in single molecule magnetism, including using f-SIMs as potential spin qubits for quantum computers.

Molecular nanomagnets have been undergoing development for 20 years since the first single-molecule magnet (SMM), Mn 12 Ac, was characterized as the molecule-behaved magnet. The multi-disciplinary scientists promoted the magnetic characteristics to be more suitable for use in information science and spintronics. The concept of molecular nanomagnets has also evolved to include single-chain magnets (SCMs), single-ion magnets (SIMs) and even magnetic molecules that showed only slow magnetic relaxation, in addition to the initial cluster-type SMMs. In this review, several aspects, including SMMs, SCMs and SIMs, are introduced briefly through some representative examples. In particular, the contribution of Chinese chemists is highlighted in the design, synthesis and understanding of various types of molecular nanomagnets.

Abstract. Molecular magnetism is producing new types of materials which cover up to date aspects of basic science together with possible applications. This article highlights recent results from the point of view of lanthanides which are now intensively used to produce single molecule magnets, single chain and single ion magnets. After a short introduction reminding the main steps of development of molecular magnetism, the basic properties of lanthanides will be covered highlighting important features which are enhanced by the electronic structure of lanthanides, like spin frustration and chirality, anisotropy and non collinear axes in zero and one dimensional materials. A paragraph of conclusions will discuss what has been done and theperspectives to be expected. A Nano history of molecular magnetismMolecular magnetism is a relatively recent section of magnetism which evolved from magnetochemistry. Magnetochemistry is the use of magnetic measurements in order to obtain structural information. An example should explain. Nickel(II) has a configuration 3d 8 . A compound with four ligands can have either a tetrahedral or square planar coordination geometry. A ligand field description shows that the five degenerate d orbitals in cubic symmetry remove their degeneracy due to low symmetry effects. The tetrahedral field is weaker than the square planar and the latter forces the electron spins to pair, while the weak tetrahedral keeps two electrons unpaired. A simple magnetic measurement at room temperature decides about the coordination structure. In fact the tetrahedral nickel (II) complexes are paramagnetic and square planar are diamagnetic. A useful technique but nothing more.The change occurred from the 60s of last century when it was realized that molecular chemistry could yield new types of magnetic materials, following the same type of evolution which took place on conductors where the introduction of molecular techniques determined a technological breakthrough.The goal at the beginning was to design and synthesize high T organic ferromagnets, but the challenge appeared soon to be too difficult and in order to start from a less hard field the goal was broadened rapidly to molecular ferromagnets i.e. to materials which may contain metal ions together with organic molecules. The results were promising, teaching how to develop strategies to design and synthesize ferro-or ferri-magnetic coupled molecules. The result was the production of low dimensional magnets while 3D materials were more difficult and the number of molecular magnets working at room temperature did not exceed 2 [1-4]. The critical temperatures of pure organic ferromagnets are still in the 30 K range.Luckily in those years there was a keen interest among physicists towards low D magnets and the exotic molecular magnets attracted the interest of quite a few. The problem was the different languages of the two communities. Physicists for instance needed one-dimensional antiferro-magnets with S> ½ to test the Haldane theory, and the only systems they we...
