Quenching of an antiferromagnet into high resistivity states using electrical or ultrashort optical pulses (2020)
Journal Article

Antiferromagnets are of potential use in the development of spintronic devices due to their ultrafast dynamics, insensitivity to external magnetic fields and absence of magnetic stray fields. Similar to their ferromagnetic counterparts, antiferromagn... Read More about Quenching of an antiferromagnet into high resistivity states using electrical or ultrashort optical pulses.

Magneto-Seebeck microscopy of domain switching in collinear antiferromagnet CuMnAs (2020)
Journal Article

Antiferromagnets offer spintronic device characteristics unparalleled in ferromagnets owing to their lack of stray fields, THz spin dynamics, and rich materials landscape. Microscopic imaging of antiferromagnetic domains is one of the key prerequisit... Read More about Magneto-Seebeck microscopy of domain switching in collinear antiferromagnet CuMnAs.

Crystal time-reversal symmetry breaking and spontaneous Hall effect in collinear antiferromagnets (2020)
Journal Article

Electrons, commonly moving along the applied electric field, acquire in certain magnets a dissipationless transverse velocity. This spontaneous Hall effect, found more than a century ago, has been understood in terms of the time-reversal symmetry bre...

Spin flop and crystalline anisotropic magnetoresistance in CuMnAs (2020)
Journal Article

We report magnetic-field-induced rotation of the antiferromagnetic Néel vector in epitaxial CuMnAs thin films. First, using soft x-ray magnetic linear dichroism spectroscopy as well as magnetometry, we demonstrate spin-flop switching and continuous s...
