      abstract     = {Magnetic singularities, also known as magnetic monopoles or
                      Bloch points, represent intriguing phenomena in
                      nanomagnetism. We show that a pair of coupled Bloch
                      points—a dipole string—may appear as a stable state in
                      cubic chiral magnets. Analysis of the thermodynamic
                      stability of such objects in the interior of crystals and in
                      geometrically confined systems is presented. Employing
                      advanced Monte Carlo simulations, we reveal an effect of
                      spontaneous nucleation of dipole strings with characteristic
                      size on the order of the helix pitch at temperature close to
                      the paramagnetic phase transition. Such behavior of chiral
                      magnets at elevated temperature drastically distinguishes
                      them from ordinary ferromagnets and may provide a
                      significant contribution to the topological Hall effect even
                      in the absence of skyrmions.},
