The Kondo effect in magnetic impurities and ferromagnetic contacts
Hyunsoo Yang, See-Hun Yang, Grzegorz Ilnicki +2
Planar macroscopic magnetic tunnel junctions exhibit well defined zero bias anomalies when a thin layer of ferromagnetic CoFe(B) nanodots is inserted within a MgO based tunnel barr…
Spin wave assisted current induced magnetic domain wall motion
Mahdi Jamali, Hyunsoo Yang, Kyung-Jin Lee
The interaction between the propagating spin waves and the current driven motion of a transverse domain wall in magnetic nanowires is studied by micromagnetic simulations. If the s…
Effect of nonadiabatic spin transfer torque on domain wall resonance frequency and mass
Mahdi Jamali, Kyung-Jin Lee, Hyunsoo Yang
The dynamics of a magnetic domain wall in a semi circular nanowire loop is studied by an analytical model and micromagnetic simulations. We find a damped sinusoidal oscillation of…
Surface energy engineering of graphene
Young Jun Shin, Yingying Wang, Han Huang +5
Contact angle goniometry is conducted for epitaxial graphene on SiC. Although only a single layer of epitaxial graphene exists on SiC, the contact angle drastically changes from 69…
Ambipolar bistable switching effect of graphene
Young Jun Shin, Jae Hyun Kwon, Gopinadhan Kalon +4
Reproducible current hysteresis is observed in graphene with a back gate structure in a two-terminal configuration. By applying a back gate bias to tune the Fermi level, an opposit…
Tunneling characteristics of graphene
Young Jun Shin, Gopinadhan Kalon, Jaesung Son +5
Negative differential conductance and tunneling characteristics of two-terminal graphene devices are observed before and after electric breakdown, respectively. The former is cause…
