Uniaxial magnetic anisotropy typically arises from either magnetocrystalline anisotropy or shape anisotropy. Here, Mohapatra et al, starting from low anisotropy and coercivity nanoparticles, show how under compression, nanoparticle chains/arrays form which exhibit significantly enhanced uniaxial anisotropy.
