Strain induced magnetic phase behavior of a frustrated helimagnet

Strain provides an exciting non-thermal parameter for exploring the rich phase diagrams of complex magnetic materials. Such systems are often characterized by a delicate balance between frustrated exchange interactions, magnetocrystalline anisotropy, and dipolar interactions, which can be strongly sensitive to uniaxial lattice distortions. Here we employ strain to traverse the phase diagram of EuIn2As2, a frustrated metallic helimagnet, under a magneto-optical probe. Our work demonstrates an efficient method of strain engineering magnetic materials and opens the door to tuning non-equilibrium magnetic phenomena such as spin transport.
