We present synchrotron x-ray diffraction, neutron powder diffraction, and time-of-flight
inelastic neutron scattering measurements on the rare earth pyrochlore oxide Nd 2 Zr 2 O 7 …

The in-plane magnetic penetration depth, λ (T), was measured down to 0.4 K in single
crystals of electron-doped superconductors, Pr 1.85 Ce 0.15 CuO 4− δ (PCCO) and Nd 1.85 …

We report the synthesis of powder and single-crystal samples of cerium pyrohafnate and
their characterization using neutron diffraction, thermogravimetry and x-ray absorption …

In conventional superconductors, the interaction that pairs the electrons to form the
superconducting state is mediated by lattice vibrations (phonons). In high-transition …

During the past 30 years materials science has developed into a full-fledged field for basic
and applied scientific enquiry. Indeed, materials scientists have devoted their efforts to …

The remarkable discovery of superconductivity above 30 K in the La-Ba-Cu-O system
(Bednorz and MUller 1986, Mtiller and Bednorz 1987, Bednorz et al. 1987a, 1987b, 1987c) …

We report the low temperature magnetic properties of the pyrochlore Pr 2 Hf 2 O 7.
Polycrystalline and single-crystal samples are investigated using time-of-flight neutron …

We report a detailed study of single-ion anisotropy and crystal-field effects in rare-earth
cuprates R 2 CuO 4 (R= Nd, Pr, and Sm). It is found that most of the magnetic properties are …

Abstract Single-crystalline N d 1.84 C e 0.16 Cu O 4 with a superconducting transition
temperature of 19.3 K has been studied above and below T c using polarized Raman …

Neutron time-of-flight spectroscopy has been employed to study the crystal-field splitting of
Pr 3+ in the pyrochlore stannate Pr 2 Sn 2 O 7. The crystal field has been parameterized …
