21.12.2022 Joint Publication about Magnetoelastic Antiferromagnets

A joint publication with Helen Gomonay about  domains the canted antiferromagnet hematite has been published in Physical Review B.

They study the domain structure of hematite and the influence of destressing fields on the magnetic domain structure. They find fluctuating destressing fields throughout the sample which leads to locally varying effective anisotropies. This effect strongly distinguishes such canted antiferromagnets from collinear ones and gives a foundation for further studies.

08.12.2022 Publication about Altermagnetism

A publication of Jairo Sinova, Libor Šmejkal and Thomas Jungwirth about altermagnetism, a new nonrelativistic magnetic phase has been published in Physical Review X.

A few month ago a new magnetic phase (altermagnetism) has been proposed. Altermagnets have zero net magnetization (like antiferromagnets) yet spin split electronic bands (like ferromagnets). This paper describes the theoretic framework and orders recent research in the emerging field.
