I do not wonder, because Stefan is right and a database for ferrites usually indicates cubic structures:  ;-)

This is depend on the characteristics of Braves lattice because each one has optimize properties different from others. 

Now that we've got the basics correct, let me tip the scale then :-)

How about for SiC or GaAs? Are (004) & (400) and (224) & (422) and (113) & (311) for Si identical? What is the convention for the choice of displaying the lowest among the indices first?

Ravi You're right, but it was probably here to polycrystal diffraction. With single crystals, one must of course to take care in particular for GaAs ...

OK! Then let us powder the wafer just a bit, like most prefer anyway, then twist some preferred orientation into it :-) What then?

Thanks Volker! Glad you included the .txt file :-) What is the practical implication of the "Phase [deg]" term?

Where do I find such data for other materials like Si, SiC (4H & 6H), TeO2, SiGe, LaSrAlO4, LaSrCuO4, Ge, & Aluminum?

@Ravi: You're right as usual! But, that's not a question of you but tather a final examination, the answer of course you know. If you have until Monday, no one answered, I must do it probably.

The data you get through CrystalMaker (+SingleCrystal + CrystalDiffract). If you and not your rabbit some seriously need then I send it naturally. But much of it is actually not cubic in my database.

Thanks a million Volker!

What about my tortoise? Don't forget the equal opportunity thing :-)
