Cyclotron resonance (CR) of two-dimensional holes is observed in the magneto transmission of circularly polarized far-infrared radiation through two InAs{sub 0.15}Sb{sub 0.85}/InSb strained-layer superlattice samples at 4.2 K. Effective masses are (0.034{plus minus}0.004){ital m}{sub {ital e}} and (0.054{plus minus}0.006){ital m}{sub {ital e}} at a hole density of 9.4{times}10{sup 10}/cm{sup 2} per quantum well. This observation is direct evidence that the energy-band line-up of the InAs{sub 0.15}Sb{sub 0.85}/InSb strained-layer superlattice is type II. In addition, a spin resonance is observed in the hole CR-inactive polarization from which an effective {ital g} factor of 140 is deduced.
