The Kondo effect in ferromagnetic atomic contacts
M. R. Calvo, J. Fernández-Rossier, J. J. Palacios +3
Iron, cobalt and nickel are archetypal ferromagnetic metals. In bulk, electronic conduction in these materials takes place mainly through the and electrons, whereas the mag…
The origin of hysteresis in resistive switching in magnetite is Joule heating
A. A. Fursina, R. G. S. Sofin, I. V. Shvets +1
In many transition metal oxides the electrical resistance is observed to undergo dramatic changes induced by large biases. In magnetite, FeO, below the Verwey temperature,…
Local-moment ferromagnetism and unusual magnetic domains in FeTaS crystals
M. D. Vannette, S. Yeninas, E. Morosan +2
Single crystals of FeTaS have been studied by using magneto-optical (MO) imaging and radio-frequency (rf) magnetic susceptibility, . Real time MO images reveal unu…
Fermi liquid state and enhanced electron correlations in the new iron pnictide CaFeAs
Liang L. Zhao, Tanghong Yi, James C. Fettinger +2
The newly discovered CaFeAs system displays low-temperature Fermi liquid behavior, with enhanced electron-electron correlations. At high temperatures, the magnetic suscepti…
