Re: Le Bail vs Rietveld for crystallite size and cell parameters?

Hi ! I have worked with both methods in ZnO, I have found that it is easier work with Le Bail or Pawley when you are looking for size strain and lattice parameters, because you just need some data about the crystal structure. But this is just an specific case. Best wishes Miguel Hesiquio-Garduño

Re: Peak shape

Hi Vengadesh you can adjust the profile ( just single peak ) with pseudo-Voigt function ( I have done it) , but if you want do a whole pattern fitting I think a pearson VII should be better best wishes Miguel Hesiquio Dear All, We took an x-ray diffraction data using Vantec

Re: wavelenght issue!

, the programm will calculate two corresponding peaks for any given Bragg reflection, using the intensity ratio given. Daniel Toebbens Institute of Mineralogy and Perography University of Innsbruck, Austria Miguel Hesiquio-Garduño Profesor Titular A Departamento de Ciencia de Materiales

Re: integrated intensity

Hi Joy! you can use Fullprof ( The interface Winplotr), but i think that in first place you should made a qualitative analysis, in order to know the crystalline phases, best wishes Miguel Hesiquio-Garduño Profesor Titular A Departamento de Ciencia de Materiales Academia de Ciencias de la

Re: Size Strain in GSAS

Hi, maybe I'm late in the discussion, but what about if we use a Rietveld ( or whole pattern fitting) refinement in order to extract data for the profile and use it to make the extraction of size and strain effects? thanks and greetings Miguel Hesiquio-Garduño Profesor Asociado C Departamento

Re: question about the Scherrer method

Hi I think that is very difficult obtain a free-strain material, and we can not neglect this effect, and it is very useful work with integral breadth rahter tan FWHM, and you should use a reference material in order to obtain the breadth due the instrument, because if you only take in

Re: Occupation in Fullprof

hope this help you. Miguel Hesiquio-Garduño Profesor Asociado C Departamento de Ciencia de Materiales Academia de Ciencias de la Ingeniería ESFM-IPN Hello to everybody. I'm trying to rifene the mixed phase Y1-xLaxBa2Cu3O7 with fullprof. For the YBaCu2O7 phase the occupation factor for Y site
