Ferromagnetic Cluster Glass Phase Embedded in a Paramagnetic and Metallic Host in Non-Uniform Magnetic System CaRu sub( 1-x)Sc sub( x)O sub( 3)
We have investigated both static and dynamic magnetic properties of polycrystalline CaRu...Sc...O... system in order to clarify the role of Sc ions as a disorder for magnetic ordering.

| description | We have investigated both static and dynamic magnetic properties of polycrystalline CaRu...Sc...O... system in order to clarify the role of Sc ions as a disorder for magnetic ordering. We have observed typical features of a ferromagnetic cluster glass state below around 40 K: (i) a broad, frequency-dependent peak in the ac magnetic susceptibility, (ii) a slow relaxation of the magnetization, and (iii) a continuous increase in the dc magnetic susceptibility in field cooling process. The composition dependence of characteristic parameters for the cluster glass state suggests that chemical segregation can hardly explain the clustering mechanism. We propose a possible picture that the ferromagnetic clusters are distributed uniformly and form the glassy state embedded in the paramagnetic and metallic host of CaRuO...
