Half-metallic ferromagnetic (HMF) materials show high spin polarization and are therefore
interesting to researchers due to their possible applications in spintronic devices. In these …

Point-contact spectroscopy was originally developed for the determination of the electron–
phonon spectral function in normal metals. However, in the past 20 years it has become an …

In this paper, we report the signature of spin gapless semiconductor (SGS) in CoFeMnSi that
belongs to the Heusler family. SGS is a new class of magnetic semiconductors which have a …

The recent experimental progress in spin-polarized scanning tunnelling microscopy (SP-
STM)—a magnetically sensitive imaging technique with ultra-high resolution—is reviewed …

Andreev reflection at a Pb/CrO 2 point contact has been used to determine the spin
polarization of single-crystal CrO 2 films made by chemical vapor deposition. The spin …

Topological superconductors represent a newly predicted phase of matter that is
topologically distinct from conventional superconducting condensates of Cooper pairs. As a …

We have measured the nonlocal resistance of aluminum-iron spin-valve structures
fabricated by e-beam lithography and shadow evaporation. The sample geometry consists …

Since the discovery of superconductivity in the high-transition-temperature (high-T c) copper
oxides two decades ago, it has been firmly established that the CuO2 plane is essential for …

Electrical currents flowing in ferromagnetic materials are spin-polarised as a result of the
spin-dependent band structure. When the spatial direction of the polarisation changes, in a …

We report the structure, magnetic property, and spin polarization of CoFeMnGe equiatomic
quaternary Heusler alloy. The alloy was found to crystallize in the cubic Heusler structure …
