Field to energy value conversion #57

Closed PkRPintu closed 4 years ago

PkRPintu commented 4 years ago

Hi,

Does anyone know how to convert the values of Uniaxial Anisotropy strength (K) and RKKY exchange coupling strength (sigma) from field to energy. I know the values in Tesla or A/m and want to convert it to Joules/m^3 for Uni Axial Anisotropy (K) and Joules/m^2 for RKKY strength (sigma) to use in the Ubermag simulation. I am used to these terms in field units and first time switching to energy term for the simulation purpose, so please do let me know. Thanks a lot for the help.

Best wishes

Hi @PkRPintu, I think I am not sure I understand you question. The energy density (J/m3) you can get directly by multiplying magnetisation and effective field (A/m). Alternatively, you can directly call oc.compute function. Please refer to tutorials from the workshop for details and slides for relevant formulas.

Does that answer your question? If not, please reopen the issue.
