The present invention is related to methods for and devices for electrical spin detection. A method for spin detection of charged carriers having a spin and forming a flux in a medium is disclosed, comprising measuring a first current on a first contact on said medium that has a first spin selectivity, measuring a second current on a second contact on said medium that has a second spin selectivity, comparing said first current and said second current, and deriving the average or statistically relevant spin state of said flux of charge carriers. Corresponding devices are disclosed. Other embodiments of the present invention disclose a method for spin detection of charged carriers having a spin and forming a flux in a medium, said flux having active and inactive periods comprising determining a starting time and place, determined as the last moment in time at which said spin of said charge carriers is statistically controlled for an active period, measuring a current in a first contact on said medium that has a certain spin selectivity over a certain period in time, and deriving the average or statistically relevant spin state of said period of flux of charge carriers.
