Magnetic order in the pseudogap phase of high- superconductors
B. Fauque, Y. Sidis, V. Hinkov +4
One of the leading issues in high- superconductors is the origin of the pseudogap phase in underdoped cuprates. Using polarized elastic neutron diffraction, we identify a nove…
Magnetic relaxation of exchange biased (Pt/Co) multilayers studied by time-resolved Kerr microscopy
Fabien Romanens, Stefania Pizzini, Fabiano Yokaichiya +8
Magnetization relaxation of exchange biased (Pt/Co)5/Pt/IrMn multilayers with perpendicular anisotropy was investigated by time-resolved Kerr microscopy. Magnetization reversal occ…
Field-induced non-Fermi-liquid resistivity of stoichiometric YbAgGe single crystals
P. G. Niklowitz, G. Knebel, J. Flouquet +2
We have investigated hexagonal YbAgGe down to 70 mK by measuring the magnetic-field and temperature dependence of the resistivity rho of single crystals in fields up to 14 T. Our r…
Magnetic density of states at low energy in geometrically frustrated systems
A. Yaouanc, P. Dalmas de Reotier, V. Glazkov +6
Using muon-spin-relaxation measurements we show that the pyrochlore compound Gd2Ti2O7, in its magnetically orderered phase below ~ 1 K, displays persistent spin dynamics down to te…
Magnetic relaxation measurements of exchange biased (Pt/Co) multilayers with perpendicular anisotropy
Fabien Romanens, Stefania Pizzini, Jordi Sort +6
Magnetic relaxation measurements were carried out by magneto-optical Kerr effect on exchange biased (Pt/Co)5/Pt/FeMn multilayers with perpendicular anisotropy. In these films the c…
Quantum Critical Point of Itinerant Antiferromagnet in Heavy Fermion
Hiroaki Kadowaki, Yoshikazu Tabata, Masugu Sato +3
A quantum critical point (QCP) of the heavy fermion Ce(Ru_{1-x}Rh_x)_2Si_2 (x = 0, 0.03) has been studied by single-crystalline neutron scattering. By accurately measuring the dyna…
