Low Lying Spin Excitation in the Spin Ice Ho2Ti2O7

Description

The high flux and low background of the new backscattering spectrometer at the SNS combine to produce an excellent signal to noise ratio, allowing us to investigate a low lying weak excitation never seen before in the spin ice, Ho2Ti2O7. This non-dispersive excitation has been observed at E = 26.3 μeV below 100 K but is resolution limited only below ∼65 K. It is indifferent to magnetic fields below μ0H = 4.5 T, at 1.6 K. These characteristics help us to identify the excitation as due to the nuclear spin system.
