Magnetostriction refers to the contraction or expansion of the crystal lattice of a magnetic material when a magnetic field is applied. Here, Meng et al show that Mn3Sn, a noncollinear antiferromagnet, hosts a large linear magnetostriction, which is driven by the field induced in-plane rotation of spins.
