Magnetic Force Scanning Tunneling Microscope Imaging of Overwritten Data
نویسندگان
چکیده
The magnetic force scanning tunneling microscopy is briefly discussed and demonstrated to successfully image overwritten data on commercial rigid magnetic disks. In particular, clear images of unerased remnants of the previously stored data are presented. These unerased data are attributed to slight radial deviations in write head tracking due to the intrinsic limitations in the electromechanical positioning of the head.

During the past two decades, there have been tremendous developments in near-field imaging and local probing techniques. Examples are the Scanning Tunneling Microscope (STM), Atomic Force Microscope (AFM), Near-field Scanning Optical Microscope (NSOM), Photon Scanning Tunneling Microscope (PSTM), and Scanning Thermal Microscope (SThM).Results showed that the average reflectance for a dopant con...
متن کاملCurrent-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...

Atomic force microscopy or scanning tunneling microscopy (AFM/STM) is a powerful single molecule tool for the visualization of biological materials at sub-nanometer resolution. AFM is versatile because it can directly measure physical properties due to its sensitivity at picoNewton force scales, thus enabling dissection of molecular forces. STM/AFM has been considered revolutionary since its di...

Reproducible scanning tunneling microscope and atomic force microscope images of entire molecules of uncoated plasmid DNA chemically bound to surfaces are presented. The chemically mediated immobilization of DNA to surfaces and subsequent scanning tunneling microscope imaging of DNA molecules demonstrate that the problem of molecular instability to forces exerted by the probe tip, inherent with...
متن کاملA modular designed ultra-high-vacuum spin-polarized scanning tunneling microscope with controllable magnetic fields for investigating epitaxial thin films.
A room-temperature ultra-high-vacuum scanning tunneling microscope for in situ scanning freshly grown epitaxial films has been developed. The core unit of the microscope, which consists of critical components including scanner and approach motors, is modular designed. This enables easy adaptation of the same microscope units to new growth systems with different sample-transfer geometries. Furth...
