We report that sizable single crystals of BaFe 2 As 2 have been grown with the self-flux
method. Measurements and anisotropy of intrinsic transport and magnetic properties from …

We report the observation of a stepwise “melting” of the low-temperature Na-vacancy order
in the layered transition-metal oxide Na 0.7 CoO 2. High-resolution neutron powder …

Sodium-ion self-diffusion in P 2 (γ)-Na x CoO 2 has been studied using a single crystal as an
electrode. Mass transport and thermodynamic properties of Na ions were measured by the …

Functional oxides have a wide variety of applications in the electronic industry. The
discovery of new metal oxides with interesting and useful properties continues to drive much …

The high temperature phase transition in the three-layered P′ 3-Na x CoO 2 (x∼ 0.62) has
been investigated by means of heat capacity measurement, x-ray diffraction, and N 23 a …

Abstract We report 23 Na and 59 Co nuclear magnetic (NMR) and quadrupolar resonance
(NQR) studies for the x= 2/3 phase of the lamellar oxide Na x CoO 2, which allowed us to …

Using N 23 a NMR measurements on sodium cobaltates at intermediate dopings (0.44≤ x≤
0.62), we establish the qualitative change in behavior of the local magnetic susceptibility at …

In the rich phase diagram of Na x CoO 2, x= 0.71 enjoys special stability and is called the
Curie-Weiss metal due to its anomalous properties. Similarly, x= 0.84 prepared from high …

We present an angle-resolved photoelectron spectroscopy study of YBa 2 Cu 3 O 7-δ films
in situ grown by pulsed laser deposition. We have successfully produced underdoped …

Lamellar A x CoO2 cobalt double oxides with A= Li, Na, and K (x∼ 0.6) have been
synthesized and their chemical (alkali content, oxidation state, and structure) and physical …
