Hybrid Organic‐Inorganic Multilayer Compounds: Towards Controllable and/or Switchable Magnets

Theoretical Determination of Multiple Exchange Couplings and Magnetic Susceptibility Data in Inorganic Solids: The Prototypical Case of Cu2(OH)3NO3

“…1,2 Hybrid organicinorganic compounds have opened an alternative route to the implementation of controllable nanomagnets by combining at the nanometer-scale molecular species and inorganic layered networks. [3][4][5][6][7] Outstanding examples are the layered transition metal hydroxides M 2 (OH) 3 X (M, divalent metal; X, exchangeable anion). These systems exhibit tunable magnetic behaviors depending on the nature of the inserted species, the character of the in-plane and interplane interactions, and the interlayer separations.…”

“…These systems exhibit tunable magnetic behaviors depending on the nature of the inserted species, the character of the in-plane and interplane interactions, and the interlayer separations. [5][6][7][9][10][11][12] Due to these different contributions, a precise understanding of magnetism at the atomic scale cannot rely on approximations based on the superposition of quasi isolated magnetic entities. This calls for the application of solid-state chemistry theoretical approaches to evaluate available fingerprints of the magnetic character, such as the magnetic susceptibility.…”

Strengthening the Magnetic Interactions in Pseudobinary First-Row Transition Metal Thiocyanates, M(NCS)2

“…If single-layer Ni(NCS)2 retains the same ordering pattern as the bulk material, these single-layer ferromagnets may have applications as magnetoelectronic devices, ferromagnetic light emitters 70,71 and hybrid multilayer materials, 72,73 motivating future synthetic studies.…”

“…Recent work on CrI 3 and Cr 2 Ge 2 Te 6 has shown that mechanical exfoliation of layered ferromagnets can generate single-layer magnets. − While bulk Ni­(NCS) 2 orders as a three-dimensional antiferromagnet, the combination of ferromagnetic intralayer order with weak interlayer interactions suggests that monolayers of this may host single-layer ferromagnetism, provided there is sufficient anisotropy. These single-layer ferromagnets may have applications as magnetoelectronic devices, ferromagnetic light emitters, , and hybrid multilayer materials, , motivating future synthetic studies.…”

The role of 2D/3D spin-polarization interactions in hybrid copper hydroxide acetate: new insights from first-principles molecular dynamics

“…Copper hydroxide acetate Cu 2 (OH) 3 CH 3 COO·H 2 O (CuOHAc) is the precursor of a whole class of hybrid organic–inorganic materials that are made of inorganic sheets separated by alkyl chains (such as alkyl sulfates and carboxylates) or conjugated molecules (such as fluorene phosphonates) [ 1 – 3 ]. The interest in Cu 2 (OH) 3 X systems stems from their tunable magnetic properties, strongly dependent on the nature of the organic ligands.…”
