The present invention is intended to prevent the deterioration of resolution due to increase in off-axis aberration resulting from the deviation of a primary electron bean from the optical axis of a scanning electron microscope. The magnetic tunnel junction may according to the invention comprise a bottom lead coupled to a bottom electrode which is coupled to a diluted magnetic semiconductor coupled to a top electrode being coupled to a top lead, wherein said bottom electrode is non magnetic. PTA-11561, a variant thereof, or a progeny thereof, as further described herein. The amplificationphase controllers control the amplification gain and phase of the wireless signal that is received via at least one antenna. The switch interchanges the plurality of channels of the parallel data signals so as to reduce a total skew as a sum of the first skew and the second skew.
