Zener model description of ferromagnetism in zinc-blende magnetic semiconductors

Science, 2000
Ferromagnetism in manganese compound semiconductors not only opens prospects for tailoring magnetic and spin-related phenomena in semiconductors with a precision specific to III-V compounds but also addresses a question about the origin of the magnetic ...

Tunable Room-temperature Ferromagnetism in two-dimensional Cr2Te3.

Nano letters (Print), 2020
The manipulation of magnetism provides a unique opportunity for the development of data storage and spintronic applications. Until now, electrical control, pressure tuning, stacking structure dependence and nanoscale engineering have been realized ...

Coexistence of Ferromagnetism and Paramagnetism in a Ferromagnetic Monolayer

Physical Review Letters, 2008
The ferromagnetic-paramagnetic phase transition in an Fe monolayer grown on a 2 ML Au/W(110) substrate and capped with a 1 ML Au layer was studied with spin polarized low electron energy microscopy. When the data are analyzed as in previous studies, not only the Curie temperature T(C) but also the effective critical exponent beta depends upon the ...

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.

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.

Anisotropic Superexchange Interaction and Weak Ferromagnetism

, 1960
A theory of anisotropic superexchange interaction is developed by extending the Anderson theory of superexchange to include spin-orbit coupling. The antisymmetric spin coupling suggested by Dzialoshinski from purely symmetry grounds and the symmetric ...

Nuclear Ferromagnetism and Antiferromagnetism [PDF]

Physica B+C, 1977
Abstract This article, written for the lay reader, describes some studies, initiated in the author's laboratory in the late 1960s and pursued there for more than 15 years. The interested reader can find a full technical description in the book Nuclear Magnetism. Order and Disorder by A. Abragam and M. Goldman. The present account is an abridged version

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 ...
