Disaccommodation of permeability and/or susceptibility (DAS) on toroidal an
d strip samples of diverse nanocrystalline FeNb-based materials is investig
ated. Usually low DAS is enhanced by low crystalline share. Strip samples a
re less advantageous than toroids; however, at strong and homogeneuous anis
otropy, as the creep-induced one, the possibility to exploit DAS opens up.
