Magnetic Bistability and Nucleation of Magnetic Bubbles in a Layered 2D Organic-Based Magnet [Fe(TCNE)(NCMe)(2)][FeCl(4)] [PDF]

, 2008
The 2D layered organic-based magnet [Fe(TCNE)(NCMe)2][FeC 14] (TCNE=tetracyanoethylene) exhibits a unique macroscopic magnetic bistability between the field-cooled and zero-field-cooled states, which cannot be explained by either superparamagnetic ...

Magnetic Bistability in Molecule-based Magnetic Materials

Science, 2006
A large first-order magnetic phase transition in an organic radical, 1,3,5-trithia-2,4,6-triazapentalenyl, is described. The transition occurs with a wide thermal hysteresis loop over the temperature range 230 to 305 kelvin. The high-temperature phase is paramagnetic, and its structure consists of a uniform one-dimensional stacking of the radical.

Magnetic Hysteresis at 10 K in Single Molecule Magnet Self‐Assembled on Gold

Advanced Science, 2021
Tremendous progress in the development of single molecule magnets (SMMs) raises the question of their device integration. On this route, understanding the properties of low‐dimensional assemblies of SMMs, in particular in contact with electrodes, is a ...

A Fractional-Order Memristive Two-Neuron-Based Hopfield Neuron Network: Dynamical Analysis and Application for Image Encryption

Mathematics, 2023
This paper presents a study on a memristive two-neuron-based Hopfield neural network with fractional-order derivatives. The equilibrium points of the system are identified, and their stability is analyzed. Bifurcation diagrams are obtained by varying the

Long-Range Magnetic Ordering and Bistability in Molecular Magnetism

, 1996
Molecular magnetism is a new area of research dealing with the chemistry and physics of molecular assemblies involving open-shell molecules, and polymeric structures synthesized from molecular precursors [1]. In that sense, molecular magnetism may be considered as a supramolecular function.

Magnetic Bistability in a Submonolayer of Sublimated Fe₄ Single-Molecule Magnets

Nano Letters, 2014
We demonstrate that Fe4 molecules can be deposited on gold by thermal sublimation in ultra-high vacuum with retention of single molecule magnet behavior. A magnetic hysteresis comparable to that found in bulk samples is indeed observed when a submonolayer film is studied by X-ray magnetic circular dichroism. Scanning tunneling microscopy evidences that
