Scanning Transmission Electron Microscopy Investigation of the Structure of Multilayered Perpendicular Magnetic Tunnel Junctions

Scanning hall probe microscopy technique for investigation of magnetic properties

Scanning Hall Probe Microscopy (SHPM) is a scanning probe microscopy technique developed to observe and image magnetic fields locally. This method is based on application of the Hall Effect, supplied by a micro hall probe attached to the end of cantilever as a sensor.  SHPM provides direct quantitative information on the magnetic state of a material and can also image magnetic induction under a...

Correlative Fluorescence- and Scanning, Transmission Electron Microscopy for Biomolecular Investigation

These days, cellular and molecular biology are closely integrated due to the development of novel correlative biomolecular microscopy platforms, even though this avant-garde vision of combining different imaging tools has been around since the late 1960s. The current boom and successful application of correlative imaging methods to dissect the cell’s internal structure is progressing faster tha...

Second order anisotropy contribution in perpendicular magnetic tunnel junctions

Hard-axis magnetoresistance loops were measured on perpendicular magnetic tunnel junction pillars of diameter ranging from 50 to 150 nm. By fitting these loops to an analytical model, the effective anisotropy fields in both free and reference layers were derived and their variations in temperature range between 340 K and 5 K were determined. It is found that a second-order anisotropy term of th...
