Static magnetic susceptibility, crystal field and exchange interactions in rare earth titanate pyrochlores.

The experimental temperature dependence (T = 2-300 K) of single crystal bulk and site susceptibilities of rare earth titanate pyrochlores R(2)Ti(2)O(7) (R = Sm, Eu, Gd, Tb, Dy, Ho, Er, Yb) is analyzed in the framework of crystal field theory and a mean field approximation. Analytical expressions for the site and bulk susceptibilities of the pyrochlore lattice are derived taking into account lon...

Anisotropy-Tuned Magnetic Order in Pyrochlore Iridates.

The magnetic behavior of polycrystalline samples of Er(2)Ir(2)O(7) and Tb(2)Ir(2)O(7) pyrochlores is studied by magnetization measurements and neutron diffraction. Both compounds undergo a magnetic transition at 140 and 130 K, respectively, associated with an ordering of the Ir sublattice, signaled by thermomagnetic hysteresis. In Tb(2)Ir(2)O(7), we show that the Ir molecular field leads the Tb...

Field-induced slow magnetic relaxation in chiral seven-coordinated mononuclear lanthanide complexes.

Four couples of enantiomerically pure chiral seven-coordinated mononuclear lanthanide complexes, [(L(OEt))Dy((R,R)-Salphen)](2)·3H(2)O (1, L(OEt) = [(Cp)Co(P(O)(OEt)(2))(3)], Cp = cyclopentadiene, Salphen = N,N'-1,2-diphenylethylenebis(salicylideneiminato) dianion), [(L(OEt))Dy((S,S)-Salphen)](2)·3H(2)O (2), [(L(OEt))Dy((R,R)-5-Cl-Salcy)]·CH(3)OH·1/8H(2)O (3, Salcy = N,N'-(1,2-cyclohexanediylet...

Titanium pyrochlore magnets: how much can be learned from magnetization measurements?

We report magnetization data for several titanium pyrochlore systems measured down to 0.5 K. The measurements, performed on single crystal samples in fields of up to 7 kOe, have captured the essential elements of the previously reported phase transitions in these compounds and have also revealed additional important features overlooked previously either because of the insufficiently low tempera...

Order and disorder in the local and long-range structure of the spin-glass pyrochlore, Tb(2)Mo(2)O(7).

To understand the origin of the spin-glass state in molybdate pyrochlores, the structure of Tb(2)Mo(2)O(7) is investigated using two techniques: the long-range lattice structure was measured using neutron powder diffraction, and local structure information was obtained from the extended x-ray absorption fine structure technique. While the long-range structure appears generally well ordered, enh...
