“…They used measurements of rémanent torque curves, in which the field at large angles to the elongation of each particle is effective, to determine the distribution of the shape anisotropy for elongated yFe 2 0 3 particles in a dilute random assembly. Again, the agreement is improved as expected, but, as in reference [92], there is still a residual discrepancy. 1, the resulting distribution function f(H 0 ) should peak at critical fields H 0 close to those expected for this reversal mode.…”
