The spin ice system Dy2Ti2O7 exhibits strong frequency-dependent spin-freezing at ∼ 16 K temperature. Although it has been a matter of discussion for years, the origin of this unusual spin freezing is still unknown. The replacement of Ti with isovalent Zr leads to the dynamic magnetic ground state at low temperatures in Dy2Zr2O7 and prevents the formation of high-temperature spin freezing. Interestingly the high-temperature spin freezing re-emerges in the presence of the magnetic field. In this…

Field induced spin freezing and low temperature heat capacity of disordered pyrochlore oxide Ho$_{2}$Zr$_{2}$O$_{7}$
Spin ice materials are the model systems that have a zero-point entropy as T → 0 K, owing to the frozen disordered states. Here, we chemically alter the well-known spin ice Ho2Ti2O7 by replacing Ti
Ordered Spin Ice State and Magnetic Fluctuations in Tb~2Sn~2O~7
We have studied the spin liquid Tb{sub 2}Sn{sub 2}O{sub 7} by neutron diffraction and specific heat measurements. Below about 2 K, the antiferromagnetic liquidlike correlations mostly change to

TLDR
The frequency dependent χ(ac)(T) data of Dy1.8Ca0.2Ti2O7 show that the spin-freezing behavior is significantly influenced by Ca substitution, and no noticeable change in the insulating behavior of Dy2Ti 2O7 results from the holes produced by 10% Ca(2+) substitution for Dy(3+) ions.
Magnetic order, magnetic correlations, and spin dynamics in the pyrochlore antiferromagnet Er2Ti2O7
Er2Ti2O7 is believed to be a realization of an XY antiferromagnet on a frustrated lattice of corner-sharing regular tetrahedra. It is presented as an example of the order-by-disorder mechanism in
How ‘spin ice’ freezes
TLDR
A cooperative spin-freezing transition leading to the spin-ice ground state in Dy2Ti2O7, a site-ordered magnetic material in which the spins reside on a lattice of corner-sharing tetrahedra where they form an unusual magnetic ground state known as ‘spin ice’ is identified.
Low-temperature measurements of magnetic susceptibility and specific heat of Eu2Ti2O7—An XY pyrochlore
Abstract Magnetic susceptibility χ ¯ obtained from magnetization measurement (for fields H=0.1 and 1.0 T) of polycrystalline Eu2Ti2O7 shows two distinct features. Firstly, χ ¯ increases on cooling
Effective hyperfine temperature in frustrated Gd 2Sn 2O 7: two level model and 155Gd Mössbauer measurements
Abstract:Using 155Gd Mössbauer spectroscopy down to 27 mK, we show that, in the geometrically frustrated pyrochlore Gd2Sn2O7, the Gd3+ hyperfine levels are populated out of equilibrium. From this, we
Zero-point entropy in ‘spin ice’
Common water ice (ice Ih) is an unusual solid—the oxygen atoms form a periodic structure but the hydrogen atoms are highly disordered due to there being two inequivalent O–H bond lengths. Pauling
Dynamical crossover in 'hot' spin ice
The magnetic dynamics of the spin ice material Ho2Ti2O7 in its paramagnetic ('hot') phase have been investigated by a combination of neutron spin echo and ac-susceptibility techniques. Relaxation at
