We present PLTplot, a plotting package for PLT Scheme. PLTplot provides a basic interface for producing common types of plots such as line and vector field plots from Scheme functions and data, an advanced interface for producing customized plot types, and support for standard curve fitting. It incorporates renderer constructors, transformers from data to its graphical representation, as values...

This paper reports the correlation between film thickness, nanostructure and DC electrical properties of copper thin films deposited by PVD method on glass substrate. X-ray diffraction (XRD) and atomic force microscopy (AFM) were used for crystallography and morphology investigation, respectively. Resistivity was measured by four point probe instrument, while a Hall effects measurement system w...

Present work reports the synthesis of RE3+ (La3+, and Ce3+) Co2+ co-doped Zn0.75Cu0.25Fe2O4 samples powder using sol-gel auto combustion process. Rietveld refinement established spinel matrix with space group (F d -3 m) suggests that uniform distribution cations at tetrahedral octahedral lattice sites. The comparative study crystallite size (D) was found Scherrer's relation, plot, Williamson-Ha...

The quantum anomalous Hall system with Chern number 2 can be destroyed by sufficiently strong disorder. During its process towards localization, it was found that the electronic states will be directly localized to an Anderson insulator (with Chern number 0), without an intermediate Hall plateau with Chern number 1. Here we investigate the topological origin of this phenomenon, by calculating t...

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...
