Journal Article
Tesařová, N., Butkovičová, D., Campion, R. P., Rushforth, A. W., Edmonds, K. W., Wadley, P., …Němec, P. (2014). Comparison of micromagnetic parameters of the ferromagnetic semiconductors (Ga,Mn)(As,P) and (Ga,Mn)As. Physical review B: Condensed matter and materials physics, 90(15), Article 155203. https://doi.org/10.1103/physrevb.90.155203

We report on the determination of micromagnetic parameters of epilayers of the ferromagnetic semiconductor (Ga,Mn)As, which has an easy axis in the sample plane, and (Ga,Mn)(As,P), which has an easy axis perpendicular to the sample plane.We use an op...

Relativistic Neel-Order Fields Induced by Electrical Current in Antiferromagnets (2014)
Journal Article

We predict that a lateral electrical current in antiferromagnets can induce nonequilibrium Néel-order fields, i.e., fields whose sign alternates between the spin sublattices, which can trigger ultrafast spin-axis reorientation. Based on microscopic t... Read More about Relativistic Neel-Order Fields Induced by Electrical Current in Antiferromagnets.

Anisotropic magnetoresistance in an antiferromagnetic semiconductor (2014)
Journal Article

Recent studies in devices comprising metal antiferromagnets have demonstrated the feasibility of a novel spintronic concept in which spin-dependent phenomena are governed by an antiferromagnet instead of a ferromagnet. Here we report experimental obs... Read More about Anisotropic magnetoresistance in an antiferromagnetic semiconductor.

Room-temperature antiferromagnetic memory resistor (2014)
Journal Article
Marti, X., Fina, I., Frontera, C., Liu, J., Wadley, P., He, Q., …Ramesh, R. (2014). Room-temperature antiferromagnetic memory resistor. Nature Materials, 13(4), 367-374. https://doi.org/10.1038/nmat3861

The bistability of ordered spin states in ferromagnets provides the basis for magnetic memory functionality. The latest generation of magnetic random access memories rely on an efficient approach in which magnetic fields are replaced by electrical me...
