Non-Magnetic Alloy.

Authors: Joseph L. Abita; DEPARTMENT OF THE NAVY WASHINGTON DC
 
Abstract: A non-magnetic alloy of a volume Vcu of copper and a volume Vmn of manganese Vmn/Vcu is made equal to - Xcu/Xmn where Xcu is the susceptibility of the copper and Xmn is the susceptibility of the manganese. Vmn/Vcu is experimentally predicted to be 1.04 percent by volume. The present invention relates to a non-magnetic alloy and method for making the non-magnetic alloy. Most materials are magnetic to some degree, i.e., exhibit ferro-, ferri-, para-, or diamagnetic behavior of a degree classified by the value of magnetic susceptibility. In diamagnetic material the magnetization (resultant magnetic moment) is opposed to the applied magnetic field, while in paramagnetic material the magnetization is in the same direction. Materials in these two groups have weak magnetism compared to ferromagnetic and ferrimagnetic materials. jg p.1 and p.3
