Many emergent properties of great interest occur near a quantum critical point were a second-order transition is suppressed to zero temperature. Hence, a significant focus of current condensed matter is the study of susceptibilities and order parameters in materials that are influenced by quantum fluctuations. Structural phase transitions close to zero temperature provide ideal platforms for...
In cubic chiral magnets, the efficient coupling of magnetic skyrmion lattices to spin currents and magnetic fields permits their dynamical manipulation. When placed in a magnetic field with a slowly oscillating direction, the skyrmion lattice can be depinned, realizing a non-equilibrium state with vanishing depinning currents. With the combination of oscillating magnetic fields and applied...
The discovery of topological protected states in chiral magnets inspired a renaissance in the field of non-collinear magnetism, and led to the identification of several long-wavelength spin objects including skyrmions, merons, solitons, and chiral bobbers. Small angle neutron scattering (SANS) has provided fundamental insights of these magnetic textures in bulk materials, whose associated...
