Tuning of magnetic bistability and domain wall dynamics in magnetic microwires

A unique combination of unusual magnetic properties, such as magnetic bistability associated with ultrafast domain wall propagation or ultrasoft magnetic properties, together with excellent mechanical and corrosion properties can be obtained in amorphous

Tunneling current bistability of correlated 2D electron-hole layers

, 1998
We study the low-temperature vertical tunneling current (TC) of a system of coupled 2D electron and hole gases (2DEG, 2DHG) of equal density realized in a single-barrier GaAs/AlAs/GaAs p-i-n heterostructure under conditions of forward bias.

Two-channel optical bistability and multistability in a degenerate four-level atomic medium under a static magnetic field

Scientific Reports
In this paper, we study the formation of optical bistability (OB) and optical multistability (OM) in a degenerate four-level atomic system by an external magnetic field that is excited by a probe laser field, a coupling laser field and a signal laser ...

Magnetization dynamics in bistable systems

, 2023
The magnetization dynamics in ferromagnetic materials will depend on the specific shape of the system’s energy landscape. In most systems, the energy landscapes can be approximated as paraboloids, resulting in a typical ellipti- cal precession of the magnetization.

Unlocking n‐alk‐1‐ynes conformers: Quantum “trigger finger” versus “stiff joint” conformations

Smart Molecules, EarlyView.
Quantum chemical analysis reveals the unique function of n‐alk‐1‐yne terminus as a Quantum “Trigger Finger,” exhibiting two near‐isoenergetic conformers (Cs ${\mathrm{C}}_{s}$and C1 ${\mathrm{C}}_{1}$) locked by a symmetric high barrier. This contrasts with the lower asymmetric barrier of the conventional asymmetric “Stiff Joint” alkyl chain.

Crystalline-state reaction with allosteric effect in spin-crossover, interpenetrated networks with magnetic and optical bistability.

, 2003
A net change: A fully reversible ligand substitution involving coordination/ uncoordination of gaseous water and pyrimidine induces the repetitive allosteric transformation of three interpenetrated nets into a single three-dimensional net.

Crystal Structures and Magnetic Properties of Coordination Polymer Complexes of Metal Ions With Kojic Acid Ligands

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
One‐dimensional coordination polymers of Cu(II) and Co(II) with kojic acid show distinct chain connectivities revealed by X ray crystallography and exhibit extremely weak magnetic interactions, as supported by magnetic measurements and molecular orbital calculations. The crystal structures and magnetic properties of coordination complexes [Cu(C6H5O4)2]

Co-occurrence of conductance switching and magnetization: tuning of electrical bistability of Fe₃O₄ quantum dots by magnetic field

, 2010
We report effects of magnetic field on electrical bistability of ferromagnetic quantum dots. Here, we select Fe3O4 nanoparticles that can be magnetized. Devices based on such nanostructures exhibit conductance switching.
