Plot of critical fields

Critical fields for µMAG standard problem #2 as a function of reduced particle width, d/lex. The symbol size is approximately equal to the uncertainty in Hcrit/Ms due to the field step size. Filled and open symbols are results obtained using the constant magnetization and constant charge methods, respectively. Superimposed data points are enclosed by parentheses. Labels a--g correspond to magnetization patterns.
