Overview: Study of magnetization temperature in ferromagnetic crystals

EuO and EuS Materials are used in study. As per Weiss mean field approximation (MFA), below certain critical temperature(Tc) ferromagnetic materials have spontaneous magnetization — i.e., a sizable macroscopic magnetic moment even in the absence of an external magnetic field. The effective field acting...

Overview: Magnetic Field for Jupiter and Neptune Class exoplanets

Dynamo is the process by which a planetary magnetic field is generated through the movement of electrically conductive materials within the planet's interior. The dynamo region is identified based on the magnetic Reynolds number.At the top of this region, the maximum magnetic field is  where...

Summary of Article about Tests of the Hard X-ray Imager

The objective of HXI is to investigate how energy from the sun is released in solar flares.The relative displacement and rotation were tested from assembly to on-orbit operation and must be maintained under 36 μm and 10 arcsecs.When HXI reaches a thermal balanced state, further deformation measurements are done and collimator alignment is tested which is essential for accurate imaging.Deformation...

Overview of Article about Random illumination Microscopy (EDF-RIM)

 The objective of RIM is to compute the variance (the spread or difference) in the intensity of the images.Intensity at camera plane depends on ρ sample fluorescence density, h the Point spread function(PSF) of the optical system and S the illumination intensity and distance of the focal plane.As...

Overview of Article about Magnetic helium-rich hot star found

 Here the magnetic field was detected 200kG which is detected based on the zeeman effect. Zeeman effect: In zeeman effect, magnetic field distorts electron orbitals, which affects atomic energy levels and the transitions between them. This results in the splitting of atomic energy levels in...

Summary of Article: The topological aberrations of twisted light

 Topology describes the study of properties of spaces that are invariant under any continuous deformation.Topological aberration: It contains a high-order optical vortex which experiences not only geometrical shifts, but an additional splitting of its high-order vortex into a constellation...
