Preparation of magnetic tips for spin-polarized scanning tunneling microscopy on Fe1+ yTe

The interplay of electronic nematic modulations, magnetic order, superconductivity, and structural distortions in strongly correlated electron materials calls for methods which allow characterizing them simultaneously, to allow establishing directly the relationship between these different phenomena. Spin-polarized STM enables studying both electronic excitations as well as magnetic structure i...

4 Spin-polarized Scanning Tunneling Microscopy

We give an introduction to spin-polarized scanning tunneling microscopy (SpSTM), a magnetic imaging technique with nanometer lateral resolution. Sp-STM allows to record constant current images which represent the electron density near the sample surface and simultaneously the spin polarization of the electron density which is related to the magnetic moment. It is shown how magnetic and topograp...

Spin-polarized scanning tunneling microscopy with quantitative insights into magnetic probes

Spin-polarized scanning tunneling microscopy and spectroscopy (spin-STM/S) have been successfully applied to magnetic characterizations of individual nanostructures. Spin-STM/S is often performed in magnetic fields of up to some Tesla, which may strongly influence the tip state. In spite of the pivotal role of the tip in spin-STM/S, the contribution of the tip to the differential conductance dI...

Tight-binding model of spin-polarized tunnelling in (Ga,Mn)As-based structures

The Landauer-Büttiker formalism combined with the tight-binding transfer matrix method is used to describe the results of recent experiments: the high tunneling magnetoresistance (TMR) in (Ga,Mn)As-based trilayers and highly polarized spin injection in p-(Ga,Mn)As/n-GaAs Zener diode. For both TMR and Zener spin current polarization, the calculated values agree well with those observed experimen...

Current-induced magnetization switching with a spin-polarized scanning tunneling microscope.

Switching the magnetization of a magnetic bit by injection of a spin-polarized current offers the possibility for the development of innovative high-density data storage technologies. We show how individual superparamagnetic iron nanoislands with typical sizes of 100 atoms can be addressed and locally switched using a magnetic scanning probe tip, thus demonstrating current-induced magnetization...
