โฆ Synopsis
The method described was used to observe quantum oscillations of the surface impedance from large sections of the Fermi surface of tin. The cylindrical specimen was heated inductively by 20 kHz currents. The 'freezing-in' of the specimen in the pressure transmitting medium was carried out at liquid nitrogen temperature.

An apparatus is described which enables a specimen of liquid mercury to be introduced into a specially shaped mould at room temperature, solidified by cooling to 77 K, cold worked by surface hammering, recrystallized by anneafing at 160 K, and then strained in tension at temperatures down to 20 K. T
The components surrounding the coil are made so that they should not have any significant influence on the parameters of the tank circuit (i.e. the distance from the ends and sides of the coil to the components is not less than its diameter and radius, respectively). To change the specimen the coax
