Anisotropy of magnetic emulsions induced by magnetic and electric fields

Yury I. Dikansky、Alexander N. Tyatyushkin、Arthur R. Zakinyan2011-09-10arXiv

The anisotropy of magnetic emulsions induced by simultaneously acting electric and magnetic fields is theoretically and experimentally investigated. Due to the anisotropy, the electric conductivity and magnetic permeability of a magnetic emulsion are no longer scalar coefficients, but are tensors. The electric conduct…

Anomalous Elastic Behavior in hcp- and Sm-Type Dysprosium

Oliver Tschauner、O. Grubor-Urosevic、Przemysław Dera 等 4 位作者2011-09-09The Journal of Physical Chemistry C

The compression behavior of elemental dysprosium in the hcp- and the Sm-type phases has been examined under hydrostatic pressure. Sm-type Dy has been found about 1% denser than the hcp phase. This increase in density is due to c -axis contraction in Sm-type Dy, whereas the a -axis even expands compared with the hcp-ph…

Dissimilarity in the Folding of Human Cytosolic Creatine Kinase Isoenzymes

Yin Wang、Sha Wang、Yan-Song Gao 等 6 位作者2011-09-09PLoS ONE

Creatine kinase (CK, EC 2.7.3.2) plays a key role in the energy homeostasis of excitable cells. The cytosolic human CK isoenzymes exist as homodimers (HMCK and HBCK) or a heterodimer (MBCK) formed by the muscle CK subunit (M) and/or brain CK subunit (B) with highly conserved three-dimensional structures composed of a…

Spin State of Co Ions in Lightly Doped Strontium LaCoO3: Via Study of High-Field Induced Spin State Transition

Keisuke Sato、Akira Matsuo、Koichi Kindo 等 5 位作者2011-09-09Journal of the Physical Society of Japan

We have investigated the high field magnetization of La 1- x Sr x CoO 3 for x ≤0.05 up to µ 0 H ext = 67 T. In a dilute limit, about 30 nonmagnetic Co ions of two species (Co I and Co II in LaCoO 3 ) are converted to magnetic Co ions (Co III ) by introducing one Sr 2+ , leaving the remaining Co I and Co II little affe…
