1/f^{3/2} Spectral Density at the Phonon Bottleneck
Steven T. Bramwell
The common observation of anomalous `' relaxation with constitutes one of the enduring mysteries of condensed matter physics. Here it is shown that a spectral…
Sample shape dependence of magnetic noise
Steven T. Bramwell
Zero-field magnetic noise, characterised by the magnetic autocorrelation function , has been observed, perhaps surprisingly, to depend on sample shape . The reasons for…
Power spectrum of magnetic relaxation in spin ice: anomalous diffusion in a Coulomb fluid
D. Billington, E. Riordan, C. Cafolla-Ward +7
Magnetization noise measurements on the spin ice DyTiO have revealed a remarkable `pink noise' power spectrum below 4 K, including evidence of magnetic m…
Dynamic susceptibility and dynamic correlations in spin ice
M. I. Ryzhkin, I. A. Ryzhkin, S. T. Bramwell
Here we calculate the dynamic susceptibility and dynamic correlation function in spin ice using the model of emergent magnetic monopoles. Calculations are based on a method origina…
Experimental Proof of a Magnetic Coulomb Phase
Tom Fennell, P. P. Deen, A. R. Wildes +6
Spin ice materials are magnetic substances in which the spin directions map onto hydrogen positions in water ice. Recently this analogy has been elevated to an electromagnetic equi…
