This introduction to spintronic phenomena deals with the three major physical effects of this research field: giant magnetoresistance, tunnel magnetoresistance and spin transfer torque. This presentation aims at describing the concepts in the simplest way by recalling their historical development. The correlated technical improvements mostly concerning material issues are also described showing their evolution with time.
