Abstract
An experimental investigation is performed of the effect a non-magnetic electrically conductive Mo interlayer 5 nm thick and placed between layers of Fe and Fe3O4 in the structure of a rod–film spin emitter has on its operating efficiency. It is shown that the power of radiation can be more than doubled. It is found that the Mo layer raises the resistance of the structure. The effect the Mo layer has on the resistance is substantiated qualitatively by the emergence between layers of the structure of a contact difference of potentials different from that of the two metals.
