We report on very accurate magnetic measurements on large rare earth orthoferrites single crystals of ErFeO3 and NdFeO3. Our results show that the interaction between rare earth and iron spin system does not change during the spin-flip process. This

The BiFeO3 single crystals were grown in air in a Bi2O3/Fe2O3 flux. X-ray microanalysis, high resolution synchrotron radiation powder X-ray diffraction, and selected area electron diffraction pattern showed that these single crystals are high quality

Single-phase HoCrO3 samples were prepared using the conventional solid-state reaction. The temperature dependence of dc magnetic properties show that the ZFC and FC magnetization curves are irreversible strongly and nearly symmetrical below 141.0 K u

A useful procedure is described to rapidly obtain Bragg-reflection intensities from the FULLPROF suite, and the Bragg intensities can then be input into the GEST and the PECKCRYST programs for crystal-structure determination of small molecules. An ex

A close-contact penalty factor has been added to theGESTstructure solution from powder diffraction data software to differentiate chemically unreasonable structure models from potentially correct models. In order to eliminate the chemically unreasona
