1907-8.] Heusler’s Magnetic Alloy. 
obtained are set forth in Diagram II. Curve I. exhibits the magnetic 
quality of the material at room temperature, Curve II. its magnetic quality 
lO 
at 120° C., and so on. It will be seen that the effect of increase of 
temperature is to diminish continuously the permeability and hysteresis 
of the material. At 310° C. the specimen became practically non-magnetic.
