Popis:	It is found that increasing the frequency of an alternating magnetic field leads to an anomalous shift in the temperature maximum of the dynamic magnetic susceptibility in e-In0.24Fe1.76O3 nanowires in a direction opposite to theoretical predictions for thermally activated processes. This unusual effect can be explained in terms of a redistribution of the contributions to the dynamic magnetic susceptibility from the high- and low-temperature phases, each of which is described by a cluster glass model. The contributions of these phases to the electron spin resonance spectra are identified.
