      abstract     = {Electron waves give an unprecedented enhancement to the
                      field of microscopy by providing higher resolving power
                      compared to their optical counterpart. Further information
                      about a specimen, such as electric and magnetic features,
                      can be revealed in electron microscopy because electrons
                      possess both a magnetic moment and charge. In-plane magnetic
                      structures in materials can be studied experimentally using
                      the effect of the Lorentz force. On the other hand, full
                      mapping of the magnetic field has hitherto remained
                      challenging. Here we measure a nanoscale out-of-plane
                      magnetic field by interfering a highly twisted electron
                      vortex beam with a reference wave. We implement a recently
                      developed holographic technique to manipulate the electron
                      wavefunction, which gives free electrons an additional
                      unbounded quantized magnetic moment along their propagation
                      direction. Our finding demonstrates that full reconstruction
                      of all three components of nanoscale magnetic fields is
                      possible without tilting the specimen.},
