      abstract     = {Colloidal assembly at fluid interfaces has a great
                      potential for the bottom‐up fabrication of novel
                      structured materials. However, challenges remain in
                      realizing controllable and tunable assembly of particles
                      into diverse structures. Herein, the capillary assembly of
                      magnetic ellipsoidal Janus particles at a fluid–fluid
                      interface is reported. Depending on their tilt angle, that
                      is, the angle the particle main axis forms with the fluid
                      interface, these particles deform the interface and generate
                      capillary dipoles or hexapoles. Driven by capillary
                      interactions, multiple particles thus assemble into
                      chain‐, hexagonal‐lattice‐, and ring‐like
                      structures, which can be actively controlled by applying an
                      external magnetic field. A field‐strength phase diagram is
                      predicted in which various structures are present as stable
                      states. Owing to the diversity, controllability, and
                      tunability of assembled structures, magnetic ellipsoidal
                      Janus particles at fluid interfaces could therefore serve as
                      versatile building blocks for novel materials.},
