The Role of Grain Boundaries in Determining the Transport Properties in Magnetite

David C. Mertens, W. Montfrooij, R. J. McQueeney +2

We present magnetoresistance and Hall-effect measurements on single crystal magnetite Fe3O4 close to the Verwey transition Tv = 123.8 K. We show that the formation of grain boundar…

Electronic Structure and Magnetic Properties of Solids

S. Y. Savrasov, A. Toropova, M. I. Katsnelson +3

We review basic computational techniques for simulations of various magnetic properties of solids. Several applications to compute magnetic anisotropy energy, spin wave spectra, ma…

Topological Hysteresis in the Intermediate State of Type-I Superconductors

Ruslan Prozorov, Russell W. Giannetta, Anatolii A. Polyanskii +1

Magneto-optical imaging of thick stress-free lead samples reveals two distinct topologies of the intermediate state. Flux tubes are formed upon magnetic field penetration (closed t…

Dissipation and coherent effects in narrow superconducting channels

M. Amin Kayali, Vladimir G. Kogan, Valery L. Pokrovsky

We apply the time dependent Ginzburg-Landau equations (TDGL) to study small ac currents of frequency in superconducting channels narrow on the scale of London penetration depth…

Quantum Griffiths effects in itinerant Heisenberg magnets

Thomas Vojta, Joerg Schmalian

We study the influence of quenched disorder on quantum phase transitions in itinerant magnets with Heisenberg spin symmetry, paying particular attention to rare disorder fluctuatio…

An Exact Solution to the Time-dependent Schrodinger Equation for a Model One-dimensional Potential

Athanasios N. Petridis, Lawrence P. Staunton, Jon Vermedahl +1

Analytical solutions to the time-dependent Shrödinger equation in one dimension are developed for time-independent potentials, one consisting of an infinite wall and a repulsive de…
