摘要：

Far-infrared magneto-optical absorption measurements of InGaAs/InAlAs heterostructures were carried out to determine a zero-field spin splitting. Peak splitting due to the zero-field spin splitting can be observed in a modulation absorption signal under pulsed electric field excitation or photoexcitation. Zero-field spin splitting is found to be 9 meV in the sample. (C) 2002 Elsevier Science B.V. All rights reserved.
