  abstract = {Experimental magnetization curves for a polydisperse ferrofluid at
	various concentrations are examined
	
	using analytical theories and computer simulations with the aim of
	establishing a robust method for obtaining
	
	the magnetic-core diameter distribution function p
x. Theoretical
	expressions are fitted to the experimental
	
	data to yield the parameters of p
x. It is shown that the majority
	of available theories yield results that depend
	
	strongly on the ferrofluid concentration, even though the magnetic
	composition should be fixed. The sole
	
	exception is the second-order modified mean-field 
MMF2 theory of
	Ivanov and Kuznetsova Phys. Rev. E
	
	64, 041405 
2001 which yields consistent results over the full experimental
	range of ferrofluid concentration.
	
	To check for consistency, extensive molecular dynamics and Monte Carlo
	simulations are performed on
	
	systems with discretized versions of p
x corresponding as closely
	as possible to that of the real ferrofluid.
	
	Essentially perfect agreement between experiment, theory, and computer
	simulation is demonstrated. In addition,
	
	the MMF2 theory provides excellent predictions for the initial susceptibility
	measured in simulations.},
