Abstract
A study of anisotropic magnetoresistance (MR) has shown that the addition of Ir to Ni, Co, Fe, Fe.2 Ni.8 and Co.3 Ni.7 crystalline films causes a negative MR. These negative values occur at room temperature as well as at low temperatures. The MR as defined by 
, where the ∥ and 
refer to the direction of magnetization relative to the electrical measuring current, can have values 
cm in Co-Ir. At Ir content of 3% the ratio 
is -2.6%. Comparisons are made with other alloy systems, and the implication of negative values of 
on theoretical models is considered.
