摘要: FOR low saturating magnetic fields, the magnetoresistive effect in a polycrystalline ferromagnet is described by relation1 : where ΔR0 positive resistance change measured when electric current i oriented first normal then parallel to saturation magnetization M s ; and ϕ angle between induction. This relation has been verified for evaporated nickel films Rappeneau2.
