Curie Constant Calculator
Compute the molar Curie constant using μeff in Bohr magnetons.
How to Use This Calculator
1
Enter μeff in μB
Use the effective magnetic moment per magnetic center.
2
Set z if multiple centers
If each formula unit has z independent spins, include the count.
3
Calculate C
Result is the molar Curie constant in SI units K·m³/mol.
Formula
C = N_A z (μ_eff μ_B)² / (3 k_B)
μ_eff is in Bohr magnetons (μB); result shown in SI K·m³/mol.
About Curie Constant Calculator
Provides a quick estimate of the molar Curie constant used in Curie's law χ = C/T for paramagnets.
Frequently Asked Questions
What unit system is this?
SI units. Many texts use cgs (emu); convert carefully between systems.
What is μeff?
The effective magnetic moment per magnetic center, often in μB from experiment.
