History Dependent Phenomena in the Transverse Ising Ferroglass: the Free Energy Landscape
Ying-Jer Kao, G. S. Grest, K. Levin +3
In this paper we investigate the relationship between glassy and ferromagnetic phases in disordered Ising ferromagnets in the presence of transverse magnetic fields, . Iterative…
Onset of antiferromagnetism in heavy fermion metals
A. Schroder, G. Aeppli, R. Coldea +6
There are two views of antiferromagnets. The first proceeds from atomic physics, which predicts that atoms with unpaired electrons develop magnetic moments. In a solid, the couplin…
X-ray induced persistent photoconductivity in Si-doped AlGaAs
Yeong-Ah Soh, G. Aeppli, Frank M. Zimmermann +2
We demonstrate that X-ray irradiation can be used to induce an insulator-metal transition in Si-doped AlGaAs, a semiconductor with {\it DX} centers. The excitatio…
Mesoscale magnetism at the grain boundaries in colossal magnetoresistive films
Yeong-Ah Soh, G. Aeppli, N. D. Mathur +1
We report the discovery of mesoscale regions with distinctive magnetic properties in epitaxial LaSrMnO films which exhibit tunneling-like magnetoresistance acro…
The connection between superconducting phase correlations and spin excitations in YBaCuO: A magnetic field study
Pengcheng Dai, H. A. Mook, G. Aeppli +2
One of the most striking universal properties of the high-transition-temperature (high-) superconductors is that they are all derived from the hole-doping of their insulating…
Spin waves and electronic interactions in La2CuO4
R. Coldea, S. M. Hayden, G. Aeppli +5
The magnetic excitations of the square-lattice spin-1/2 antiferromagnet and high-Tc parent La2CuO4 are determined using high-resolution inelastic neutron scattering. Sharp spin wav…
