Critical behavior of multiferroic hexagonal RMnO3
Using a microscopic model and a Green’s function technique we have studied the critical behavior of somemultiferroics such as hexagonal RMnO3. The temperature dependence and the external field dependence of the magnetization and susceptibility are determined. The critical exponents b and g are calculated. Applying the scaling laws a, d, and n are also obtained. The critical exponents are in ver...
متن کاملStructural anomalies and multiferroic behavior in magnetically frustrated TbMn2O5.
We have studied the magnetostructural phase diagram of multiferroic TbMn2O5 as a function of temperature and magnetic field by neutron diffraction. Dielectric and magnetic anomalies are found to be associated with steps in the magnetic propagation vector, including a rare example of a commensurate-incommensurate transition on cooling below 24 K, and in the structural parameters. The geometrical...
متن کاملOrgano-fluorine chemistry III
It is a pleasure to introduce the 3rd in the series of Thematic Issues on organo-fluorine chemistry for the Beilstein Journal of Organic Chemistry (BJOC). These series have become progressively more successful over time in terms of the number and quality of the contributions received. It is also pleasing to note that the profile and impact factor of the journal has increased steadily over this ...
متن کاملOrgano-fluorine chemistry II
It is a pleasure to be able to introduce this second Thematic Series on ‘organo-fluorine chemistry’ within the Beilstein Journal of Organic Chemistry. The series now embeds the subject firmly as a special interest area of the journal. The first series in 2008 presented contributions representing a wide range of organic fluorine chemistry [1-10] and this series continues that trend exploring the...
متن کاملMagnetic Ordering-Induced Multiferroic Behavior in [CH3NH3][Co(HCOO)3] Metal-Organic Framework.
We present the first example of magnetic ordering-induced multiferroic behavior in a metal-organic framework magnet. This compound is [CH3NH3][Co(HCOO)3] with a perovskite-like structure. The A-site [CH3NH3](+) cation strongly distorts the framework, allowing anisotropic magnetic and electric behavior and coupling between them to occur. This material is a spin canted antiferromagnet below 15.9 ...
