|Title:||Evidence of Verwey transition in iron- and iron oxide-encapsulated carbon nanotubes|
|Author:||de Araujo, AEP|
|Abstract:||Magnetization measurements in two different samples of iron- and iron oxide-encapsulated carbon nanotubes are presented. The samples showed coercivity smaller than 1 kOe. The dependence of the coercivity with the temperature has an abrupt change at temperatures close to 125 K. In this temperature the ZFC and FC magnetization curves also present an abrupt change. This effect is attributed to a Verwey transition. (C)0 2006 Elsevier B.V. All rights reserved.|
