Abstract:

AbstractThe parallel susceptibility x∥ at 0 K of a double magnetic helix of pitch angle ϕ in which two species of magnetic ions are acted on by unequal molecular fields is determined. The conditions under which x∥ is equal to the 0 K perpendicular susceptibility x⊥ calculated in the past are determined. Comparison is made with the powder susceptibility measurements performed on the orthorhombic compound La2Fe1.5Mn0.5S5 which displays a double magnetic helix up to TN = 85 K.
