We present temperature-dependent magneto-transport measurements on as-grown\nand annealed YbNi2B2C single crystals. Annealing causes drastic changes\nin the Hall coefficient, RH(T). Whereas for as-grown samples the Hall\ncoefficient is negative between room temperature and 2 K, with a pronounced\n it minimum at \≈ 22 K, for the samples annealed at 950^\∘ C for\n150 hours, RH(T) changes its sign twice in the same temperature range: from\nnegative to positive on cooling below \∼ 100 K and back to negative below\n\∼ 10 K, and has a clear it maximum at \≈ 45 K. Intermediate\ntemperature dependencies can be achieved by reducing the annealing time. These\nfindings are discussed within the framework of an annealing dependence of the\nskew scattering in conjunction with the recent structural, thermodynamic and\ntransport studies of the effects of annealing in YbNi2B2C.\n
