Antiferromagnetic materials opened up a new avenue of research with potential use in spintronic devices. Compared to ferromagnets they exhibit faster dynamics, insensitivity to the external magnetic fields, and absence of stray fields promising higher integration density.
Quenching of the antiferromagnet into high resistivity states using electrical and optical pulses was recently discovered in CuMnAs material. In this contribution, we provide a detailed overview of quenching of CuMnAs using ultrashort laser pulses for excitation.
It focuses on the optimization of the response with regard to the size and position of the laser spot, pulse length, and fluence. It also provides an overview of the response for CuMnAs films with varying thickness and substrate material.
