Observation of low frequency spin dynamics in INVAR FeNi
Giovanni B Pasquino, Jon W Taylor, Sean R Giblin +3
We present ferromagnetic neutron spin echo measurements and muon spin relaxation (SR) measurements of the spin dynamics in the ordered phase of the metallic alloy INVAR Fe$_{65}…
Nuclear spin correlations and collective excitations in supercritical H
Raina J. Olsen, Jon W. Taylor, Cristian I. Contescu +1
Nuclear spins are known to experience spontaneous long-range correlations only below 2.5 mili-Kelvin in superfluid He. Here we present the first evidence of nuclear spin coupli…
Phonons and Stability of Infinite-Layer Iron Oxides SrFeO2 and CaFeO2
M. K. Gupta, R. Mittal, S. L. Chaplot +2
We present detailed ab-initio lattice dynamical analysis of the Fe-O infinite-layer compounds CaFeO2 and SrFeO2 in various magnetic configurations. These indicate strong spin-phono…
The effect of externally applied pressure on the magnetic behavior of Cu2Te2O5(BrxCl{1-x})2
S. J. Crowe, M. R. Lees, D. McK. Paul +5
The effect of externally applied pressure on the magnetic behavior of Cu2Te2O5(BrxCl{1-x})2 with x = 0, 0.73 and 1, is investigated by a combination of magnetic susceptibility, neu…
