Friedel Oscillation about a Friedel-Anderson Impurity
Yaqi Tao, Gerd Bergmann
The Friedel oscillations in the vicinity of a Friedel-Anderson (FA) impurity are investigated numerically. For an FA impurity in the local moment limit the normalized amplitude A(ξ…

Oscillations of the magnetic polarization in a Kondo impurity at finite magnetic fields
Gerd Bergmann
The electronic properties of a Kondo impurity are investigated in a magnetic field using linear response theory. The distribution of electrical charge and magnetic polarization are…

Spacial Modulation of the Magnetization in Cobalt Nanowires
Gerd Bergmann, Yaqi Tao, Jia G. Lu +1
Cobalt nanowires with a diameter in the range between 50 to 100nm can be prepared as single-crystal wires with the easy axis (the c-axis) perpendicular to the wire axis. The compet…
