MAGNETIC FIELD STRENGTH, H, IN OERSTEDS 



Fig, 7 — Change in velocity in percent from demagnetized value as a function of the 

 magnetizing field for a longitudinal wave in a (110) section when the particle velocity is 

 along the [110] direction and the field along the [001] direction. « 



developed by one of the writers^ for obtaining the elastic constants of a 

 polycrystalline rod from the cubic elastic constants. In this case the Lame 

 elastic constants are given by the formulas
