Abstract :
In this paper, a compact high magnetic field facility for cyclotron resonance (CR) investigation in the mid-infrared range is presented. A technology of multiturn coils winding with microcomposite Cu-Nb wire was developed in the Sarov Physics and Technology Institute Norwegian University of Science and Technology Moscow Engineering Physics Institute for the fabrication of compact nondestructive solenoids up to 50 T. An optical scheme and details of experimental techniques of CR measurements are discussed. Two peaks of magnetic absorption at 28 THz were observed in a narrow-gap HgTe/Hg1-xCdxTe heterostructures with quantum wells at 80 K.
