From this can we can obtain the mag.moment of any complexes and then we predict whether it is ferro or anti-ferro mag. Nature any papers or references since there is confusion that some one using hysterisis loop try to help me
VSM measures the magnetic moment of the investigated sample as a function of temperature and external magnetic field, and magnetic susceptibility is obtained by dividing the measured value of the magnetic moment of the sample by the value of magnetic field applied during the measurement. Total magnetic moment is an extensive variable and depends on the quantity of sample used during the measurement. If one knows the quantity of sample taken for measurement in VSM, it is easy to scale and obtain magnetic moment per mole (or per gram or per cc). If you are using a software which takes the quantity of sample taken as input data, software may be internally programmed to show the results of measurements with scaling desired by the user such as susceptibility per gram (or per mole or per cc); it may even provide you a choice of units in which the results are to be displayed. In this case, you need to check in the manual of VSM how the results of measurements in that particular instrument are actually scaled and displayed.
it depends on the capabilities of your particular vibromechanical. In any case, you can do the conversion, but you must consider the external shape, type of material, the dispersion of the sample, etc.
Dear Madhukar,
I am having trouble understanding some of the units used in some old magnetic studies (see first 2 attachments). I am trying to see if the susceptibility, in units of emu/(mol*Oe), of the material I'm investigating is comparable to other paramagnetic elements, but consistently old papers show the molar susceptibility reported in emu/mol. It's my understanding that emu's are units of the total magnetic moment, so emu/mol should represent the magnetic moment per mole instead of the susceptibility (emu/(mol*Oe)). Is it assumed that the values in these papers have already been normalized by the applied magnetic field?
