摘要:

When a superconducting solenoid is operated in the persistent mode, a variation in the magnetization of a sample (produced by a temperature change) enclosed by the solenoid will produce a modification in the solenoid current. Equations are developed for calculating this effect on the superconducting current and the related magnetic field change. A specific example is given on the error produced in heat capacity measurements.

摘要:

The electrical resistance behavior of a material under very high pressure can be studied by pressing the material with a diamond indentor against a diamond flat. The high pressures generated can be calculated using Hertz’s theory provided the material thickness is about a micron or less. Here we describe a method of preparing micron thick specimens of a few millimeters in size. We have prepared micron thick specimens of a few millimeters in size of Si (100), Si (111), NaCl (100). The result of high pressure study on Si (100) is also presented.
