To demonstrate this phenomenon researchers created a new kind of material called a 'non-collinear antiferromagnet
' -- Mn3Sn which is a special kind of magnet.

The temperature dependence of the magnetic susceptibility of the investigated alloys has the form characteristic for an antiferromagnet
 and makes it possible to estimate the temperature of transition to the paramagnetic state: for the [Fe.sub.65][Al.sub.30][Ga.sub.5] alloy, [T.sub.C] = 400 K, which is higher compared to the binary alloy [Fe.sub.65][Al.sub.35] ([approximately equal to]340 K).
 demonstrated that the nonlinear sigma model for a field with SO(3) symmetry gives a good description of the properties of a two-dimensional (2+1) Heisenberg antiferromagnet
in the low-temperature, long-wavelength regime.

We consider the effects of toroidal moment corrections to the acoustic susceptibility tensor of a material that is simultaneously ferroelectric and a canted antiferromagnet
Instead of lining up neatly (as in magnets and in an antiferromagnet
, left, seen in superconductors), the spins move around uncomfortably thanks to quantum fluctuations that keep them twitching even at absolute zero.
is a special kind of ferrimagnet where adjacent spin moments completely cancel.
For our experimental setup, in which the applied field is parallel to the gamma-ray direction, this is, the theoretical area ratio for an antiferromagnet
in the spin-flop state.
One of the most innovative structures he introduced involves an "artificial antiferromagnet
," a magnetic multilayered material with zero net magnetic moment yet with a ferromagnetic interface.
