This article reviews the basic theoretical aspects of graphene, a one-atom-thick allotrope of
carbon, with unusual two-dimensional Dirac-like electronic excitations. The Dirac electrons …

The phenomenon of electron tunnelling has been known since the advent of quantum
mechanics, but continues to enrich our understanding of many fields of physics, as well as …

The discovery of enhanced magnetoresistance and oscillatory interlayer exchange coupling
in transition metal multilayers just over a decade ago has enabled the development of new …

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 …

Graphene has been widely studied for its high in-plane charge carrier mobility and long spin
diffusion lengths. In contrast, the out-of-plane charge and spin transport behavior of this …

We present point-contact Andreev reflection measurements of X/N b contacts, where X= Ni,
Co, Fe, and Cu. Experimental conductance-voltage curves were analyzed with the Blonder …

Insertion of a thin nonmagnetic copper Cu (001) layer between the tunnel barrier and the
ferromagnetic electrode of a magnetic tunnel junction is shown to result in the oscillation of …

The phenomenon of quantum tunneling, which was discovered almost a century ago, has
led to many subsequent discoveries. One such discovery, spin polarized tunneling, was …

We have measured the tunneling magnetoresistance (TMR) of magnetic tunnel junctions
based on La 2/3 Sr 1/3 MnO 3 and various barrier materials (SrTiO 3, TiO 2, LaAlO 3). The …

This review focuses on the recent experimental integration of 2D materials, mostly graphene
but also h-BN and dichalochogenides, such as MoS 2 and WS 2, in magnetic tunnel …
