The magnetic moment of nanosized magnets is widely used for data storage in modern electronics. Integration of such magnets into larger circuits can be possible, if the read-out and the storage of data can be performed electrically. This can, for example, be achieved by using spin transfer torque for the definition of magnetic moment of a nanomagnet. Here, we demonstrate switching of a single magnetic pillar in a so-called current in plane geometry. The pillar structures are fabricated from CoFe layers using electron beam lithography on SiN membranes. The magnetization direction of the pillar is imaged using scanning transmission x-ray microscopy (STXM).
