Abstract

As a part of the development of an alternating-current bolometer, a method for the production of very thin nickel ribbons (and, incidentally, nickel foil) has been developed. Ribbon filaments have been prepared which are as thin as 0.1 micron. These filaments appear to possess the properties of bulk nickel. Certain properties of these filaments have been studied and are described. The method is not restricted to nickel, since bismuth ribbons have been prepared by the same procedure.
