Aa. Vertiy et al., 2-FREQUENCY QUASI-OPTICAL RADIOSPECTROMETER FOR SUBSTANCE INVESTIGATIONS, International journal of infrared and millimeter waves, 14(11), 1993, pp. 2339-2344
In this paper two-frequency radiospectrometer is described: frequency
of ESR is ne (120 GHz - 150 GHz); frequency of the nuclear magnetic re
sonance (NMR) is n(n) =(180 MHz - 200 MHz). Radiospectrometer is opera
tes in the temperature band T=(4.2 K 1.7 R) and in the magnetic field
band H=5 T.
