A Novel Synthetic Route to Transition Metal Carbonates: Magnetic Properties Revisited

We present a novel method for the preparation of transition metal carbonates that is able to provide solid solutions of controlled proportions. Unexpected magnetic properties, such as negative magnetization, for the mixed-metal solid solutions are observed that can be accounted to clustering. The ne...

Description
Summary:	We present a novel method for the preparation of transition metal carbonates that is able to provide solid solutions of controlled proportions. Unexpected magnetic properties, such as negative magnetization, for the mixed-metal solid solutions are observed that can be accounted to clustering. The negative magnetization is discussed in terms of dipolar interaction between neighboring clusters. carbonates cobalt magnetic properties nickel random fields
