An experimental measurement of the staggered magnetization curve for a Haldane spin chain
Long-range magnetic ordering in R_2 Ba Ni O_5 (R=magnetic rare earth) quasi-1-dimensional mixed-spin antiferromagnets is described by a simple mean-field model that is based on the intrinsic staggered magnetization function of isolated Haldane spin ...

Purification of LiF Powder by Zone Melting Method [PDF]
In order to achieve high quality crystals, it is necessary to purify the raw material. In the present experimental study, the zone melting method was used to purify Lithium Flouride powder. A small amount of melt moves slowly from the solid area in order

Jc Scaling and Anisotropies in Co-doped Ba-122 thin films
We have successfully grown epitaxial, superconducting films of Ba(Fe1-xCox)2As2 (Ba-122)with x ~ 0.1. The films grow without observable correlated defects parallel to the c-axis, as confirmed by TEM.

First-principle study on compensated half metallic double perovskite compound $Ba_2PrVO_6$
The first-principle study on double perovskite compound Ba$_2$PrVO$_6$ has been presented in this paper. By analysing band structures and integrated density of states, it is found that Ba$_2$PrVO$_6$ is ferromagnetic metallic within LSDA and compensated ...
