Abstract
The spin splitting in zero magnetic field between the up- and down-spin ele ctrons in a two-dimensional electron gas is obtained for a pseudomorphic In GaAs/In0.52Al0.48As graded heterostructure. We have studied the spin splitt ing in the heterostructure by means of the Shubnikov-de Haas oscillations. By analyzing the characteristic beating pattern of the oscillations, a spin splitting of 8.76 meV was determined as B --> 0.
