Neutron diffraction has been used to investigate the magnetic correlations in single crystals of the spin ice materials Ho2Ti2O7 and Dy2Ti2O7 in an external magnetic field applied along either the...
Magnetic ordering in the spin-ice candidate Ho{2}Ru{2}O{7} (2004)
Wieble, C.R., Gardner, J.S., Luke, G.M., Wills, A.S., Gaulin, D.B., ...
Neutron scattering measurements on the spin-ice candidate material Ho2Ru2O7 have revealed two magnetic transitions at T∼95 and ∼1.4 K to long-range ordered states involving the Ru and Ho...
Phase transitions, partial disorder and multi-k structures in Gd2Ti2O7 (2004)
Stewart, J.R., Ehlers, G., Wills, A.S., Bramwell, S.T., Gardner, J.S.
The geometrically frustrated antiferromagnet Gd2Ti2O7 exhibits magnetic behaviour of such complexity that it poses a challenge to both experiment and theory. Magnetic ordering commences at TN = 1.1 K...

Pressure-induced crystallization of a spin liquid (2002)
Mirebeau, I., Goncharenko, I.N., Cadavez-Peres, P., Bramwell, S.T., Gingras, M.J.P., Gardner, J.S.
Liquids are expected to crystallize at low temperature. The only exception is helium, which can remain liquid at 0 K, owing to quantum fluctuations1, 2. Similarly, the atomic magnetic moments (spins)...
