Chaos in the Ferromagnetic Phase of a Reentrant Ferromagnet

Physical Review Letters, 1996
The inherent dynamic properties of the ferromagnetic phase of a reentrant ferromagnet, (Fe{sub 0.20}Ni{sub 0.80}){sub 75}P{sub 16}B{sub 6}Al{sub 3}, have been experimentally investigated by low field magnetic relaxation and ac susceptibility measurements.

Two-dimensional itinerant ferromagnetism in atomically thin Fe3GeTe2

Nature Materials, 2018
Discoveries of intrinsic two-dimensional (2D) ferromagnetism in van der Waals (vdW) crystals provide an interesting arena for studying fundamental 2D magnetism and devices that employ localized spins1–4.

Absence of Ferromagnetism or Antiferromagnetism in One- or Two-Dimensional Isotropic Heisenberg Models

, 1966
It is rigorously proved that at any nonzero temperature, a one- or two-dimensional isotropic spin-S Heisenberg model with finite-range exchange interaction can be neither ferromagnetic nor antiferromagnetic.

Chemically Exfoliated VSe2 Monolayers with Room‐Temperature Ferromagnetism

Advances in Materials, 2019
Among van der Waals layered ferromagnets, monolayer vanadium diselenide (VSe2) stands out due to its robust ferromagnetism. However, the exfoliation of monolayer VSe2 is challenging, not least because the monolayer flake is extremely unstable in air ...

Conductance spectra of asymmetric ferromagnet/ferromagnet/ferromagnet junctions

Journal of Magnetism and Magnetic Materials, 2017
Abstract A theory of tunneling spectroscopy of ferromagnet/ferromagnet/ferromagnet junctions was studied. We applied a delta-functional approximation for the interface scattering properties under a one-dimensional system of a free electron approach.

Toward Intrinsic Room-Temperature Ferromagnetism in Two-Dimensional Semiconductors.

Journal of the American Chemical Society, 2018
Two-dimensional (2D) ferromagnetic semiconductors have been recognized as the cornerstone for next-generation electric devices, but the development is highly limited by the weak ferromagnetic coupling and low Curie temperature ( TC).

Multi-state magnetoresistance in ferromagnet/organic-ferromagnet/ferromagnet junctions

Applied Physics Letters, 2014
Spin-dependent transport through a ferromagnetic metal/organic-ferromagnet/ferromagnet metal junction is investigated theoretically. It is demonstrated that the current through the device strongly depends on the alignment of the magnetization orientations of the electrodes and interlayer.

Vacancy-induced ferromagnetism of MoS2 nanosheets.

Journal of the American Chemical Society, 2015
Outstanding magnetic properties are highly desired for two-dimensional ultrathin semiconductor nanosheets. Here, we propose a phase incorporation strategy to induce robust room-temperature ferromagnetism in a nonmagnetic MoS2 semiconductor.
