We show theoretically that π Josephson junctions may be constructed by use of antiferromagnetic (AF) metals between superconducting electrodes. We argue that the AF magnetic ordering introduces the energy difference of ...

We study, by means of the density matrix renormalization group, the infinite U Hubbard model—with one hole doped away from half filling—in triangular and square lattices with frustrated hoppings, which invalidate Nagaoka’s ...

We show that proper control of magnetization textures can be achieved in noncollinear antiferromagnets. This opens the versatile toolbox of domain-wall manipulation in the context of a different family of materials. In ...

The response of an antiferromagnetic film to incident radiation at oblique incidence is studied in the nonlinear regime. For given values of the frequency and incidence angle, the reflectivity of a film of arbitrary thickness ...

A theoretical study of mixed modes of uniaxial Heisenberg antiferromagnets by a dc field is presented. The static field is applied in an arbitrary direction relative to the easy axis and special attention is given to the ...
