Model of the low temperature magnetic phases of gadolinium gallium garnet
M. Ancliff, V. Sachnev, N. d'Ambrumenil
The magnetic behaviour of gadolinium gallium garnet in an external magnetic field at zero temperature is considered. For high fields a classical spin model of the gadolinium ions p…
Probing short-range magnetic order in a geometrically frustrated magnet by spin Seebeck effect
Changjiang Liu, Stephen M. Wu, John E. Pearson +3
Competing magnetic interactions in geometrically frustrated magnets give rise to new forms of correlated matter, such as spin liquids and spin ices. Characterizing the magnetic str…
Fractional Quantum Hall States in a Ge Quantum Well
O. A. Mironov, N. d'Ambrumenil, A. Dobbie +3
Measurements of the Hall and dissipative conductivity of a strained Ge quantum well on a SiGe/(001)Si substrate in the quantum Hall regime are reported. We find quantum Hall states…
Dispersionless spin waves in Gadolinium Gallium Garnet
N. d'Ambrumenil, O. A. Petrenko, H. Mutka +1
We report the results of neutron scattering on a powder sample of Gd3Ga5O12 at high magnetic fields. We find that in high fields (B>1.8 T) the system is not fully polarized, but ha…
Thermopower in the quantum Hall regime
N. d'Ambrumenil, R. H. Morf
We consider the effect of disorder on the themopower in quantum Hall systems. For a sample in the Corbino geometry, where dissipative currents are not carried by edge states, we fi…
Optimal pumping of orbital entanglement with single particle emitters
Y. Sherkunov, N. d'Ambrumenil, P. Samuelsson +1
We propose a method for the optimal time-controlled generation of entangled itinerant particles, using on-demand sources in a conductor in the quantum Hall regime. This entanglemen…
