Controlling orbital moment and spin orientation in CoO layers by strain.

First-principles investigations of the orbital magnetic moments in CrO2

The electronic and magnetic properties of the ferromagnetic half-metal CrO2 have been studied by using the full-potential linear muffin-tin orbital method within the local-spin-density approximation ~LSDA! and the LSDA1U approach. The orbital magnetic moments are investigated by including the spin-orbit coupling in both schemes. Compared with the orbital contributions to magnetization in other ...

Antiferromagnetic proximity effect in epitaxial CoO/NiO/MgO(001) systems

Magnetic proximity effect between two magnetic layers is an important focus of research for discovering new physical properties of magnetic systems. Antiferromagnets (AFMs) are fundamental systems with magnetic ordering and promising candidate materials in the emerging field of antiferromagnetic spintronics. However, the magnetic proximity effect between antiferromagnetic bilayers is rarely stu...

Half semimetallic antiferromagnetism in the Sr2CrTO6 system „T=Os,Ru..

Double perovskite Sr2CrOsO6 is or is very close to a realization of a spin-asymmetric semimetallic compensated ferrimagnet, according to first principles calculations. This type of near-half metallic antiferromagnet is an unusual occurrence, and more so in this compound because the zero gap is accidental rather than being symmetry determined. The large spin-orbit coupling SOC of osmium upsets t...

Chern number spins of Mn acceptor magnets in GaAs.

We determine the effective total spin J of local moments formed from acceptor states bound to Mn ions in GaAs by evaluating their magnetic Chern numbers. When individual Mn atoms are close to the sample surface, the total spin changes from J=1 to J=2, due to quenching of the acceptor orbital moment. For Mn pairs in bulk, the total J depends on pair orientation in the GaAs lattice and on the sep...
