1. A magnon tunnel junction, comprising:
a first ferromagnetic layer formed of a ferromagnetic insulation material for conducting magnons;
a first antiferromagnetic layer located on the first ferromagnetic layer and formed of an antiferromagnetic insulation material, the first antiferromagnetic layer serving as a barrier layer for magnons; and
a second ferromagnetic layer located on the first antiferromagnetic layer and formed of a ferromagnetic insulation material for conducting magnons,
wherein the ferromagnetic insulation material comprises one or more of the following materials: R3Fe5O12, MFe2O4, BaFe12O19, SrFe12O19, and doped compounds thereof, where R is Y, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb or Lu, and M is Mn, Zn, Cu, Ni, Mg or Co, and
wherein the antiferromagnetic insulation material comprises one or more of the following materials: NiO and CoO.
