Effects of Finite Lattice Heat Capacity on Spin Lattice Relaxation: Theory and Numerical Analysis

Effects of Finite Lattice Heat Capacity on Spin Lattice Relaxation: Theory and Numerical Analysis

Date: August 1, 1967
Creator: Peterson, Robert L.
Description: Report discussing the transient magnetic behavior of a paramagnetic substance, after an initial disturbance, considered theoretically for a variety of situations in which the lattice temperature rises as a result of energy flow from the magnetic (electron spin) system. Next, the opposite extreme is considered - that in which the resonant and remaining modes are totally uncoupled. Finally, there is a consideration of the case of spins coupled only to the resonant phonons, which in turn are coupled to a constant temperature bath, whether this be the helium or the remaining modes.

International Practical Temperature Scale of 1948: Text Revision of 1960

International Practical Temperature Scale of 1948: Text Revision of 1960

Date: September 8, 1961
Creator: Stimson, H. F.
Description: Report is a text revision of the International Temperature Scale of 1948; the numerical values of temperatures remain the same. The adjective "Practical" was added to the name by the International Committee on Weights and Measures. The scale continues to be based upon six fixed and reproducible equilibrium temperatures to which values have been assigned, and upon the same interpolation formulas relating temperatures to the indications of specified measuring instruments. Some changes have been made in the text to make the scale more reproducible than its predecessor. The triple point of water, with the value 0.01 ºC replaces the former ice point as a defining fixed point of the scale. It is also recommended that the zinc point, with the value 419.505 ºC, be used instead of the sulfur point. The recommendations include new information that has become available since 1948.
