With this first introduction of the metamaterial, it appears that the losses incurred were smaller than antiferromagnetic, or ferromagnetic materials.
42.
On the basis of orientation, magnetic materials are divided into five categories : Diamagnetic, Paramagnetic, Ferromagnetic, Antiferromagnetic and Ferrimagnetic
43.
The undoped " parent " or " mother " compounds are Mott insulators with long-range antiferromagnetic order at low enough temperature.
44.
The spin structure of andradite contains two mutually canted equivalent antiferromagnetic sublattices below the N�el temperature ( T N = 11 K ).
45.
The two irons are at this point oxidized to FeIV and have changed from low-spin ferromagnetic to high-spin antiferromagnetic.
46.
Nowadays, antiferromagnetic tips are in use since ferromagnetic tips induce magnetization reversal in the systems to be studied due to stray fields.
47.
Therefore, with the magnetization of this atom well defined, the tunneling current remains polarized for antiferromagnetic tips but without stray field.
48.
;Weak-coupling theory : Firstly, it has been suggested that the HTS emerges by antiferromagnetic spin fluctuation in a doped system.
49.
This is exactly equivalent to having an antiferromagnetic interaction between each pair of spins, so in this case there is no geometrical frustration.
50.
There is possibly a small region of stability for a ( frustrated ) antiferromagnetic Wigner crystal, before a further transition to a ferromagnetic crystal.
