                         the effects of current sheets in solar wind turbulence. By using 
                         multifractal detrended fluctuation analysis coupled with surrogate 
                         methods and volatility, two solar wind magnetic field time series 
                         are investigated, one with current sheets and one without current 
                         sheets. Despite the lack of extreme-events intermittent bursts in 
                         the current sheet-free series, both series are shown to be 
                         strongly multifractal, although the current sheet-free series 
                         displays an almost linear behaviour for the scaling exponent of 
                         structure functions. Long-range correlations are shown to be the 
                         main source of multifractality for the series without current 
                         sheets, while a combination of heavy-tail distribution and 
                         non-linear correlations is responsible for multifractality in the 
                         series with current sheets. The multifractality in both time 
                         series is formally shown to be associated with an energy-cascade 
                         process using the p-model.",
