Abstract
Pulsed field measurements on polycrystalline Er6Fe23 are used to determine the molecular field coefficient n = 13.5 ± 1 Mol/cm3. A comparison between the temperature dependence of the calculated lower critical field H1 = n(MA - MB) [5] and the experimental one shows the influence of the anisotropy. A similar effect can be seen if one compares the theoretical critical temperature 157 K and the experimental one, which is equal to 130 KKeywords
