摘要: In this letter, a direct measurement of “easy” magnetization switching indicating zero-magnetization remanence in magnetic probe with cross section as narrow 60×60 nm2, and tall 750 nm, is presented. Magnetic force microscopy was utilized to test focused-ion-beam-fabricated nanomagnetic probes. The data directly indicate that unlike regular solid probe, tubelike ending (nanotube) provides substantially “easier” switching.
