About

The Instituto de Ciencia de Materiales de Madrid (ICMM) is an institute of the Consejo Superior de Investigaciones Cientificas (CSIC) (Spanish National Research Council) founded in December 1986, that belongs to the Area of Science and Technology of Materials, one of the eight Areas in which the CSIC divides its research activities.

 

Our mission is to create new fundamental and applied knowledge in materials of high technological impact, their processing and their transfer to the productive sectors at local, national and European scales (the true value of materials is in their use), the training of new professionals, and the dissemination of the scientific knowledge.

A novel perovskite oxide chemically designed to show multiferroic phase boundary with room-temperature magnetoelectricity

There is a growing activity in the search of novel single-phase multiferroics that could finally provide distinctive magnetoelectric responses at room temperature, for they would enable a range of potentially disruptive technologies, making use of the ability of controlling polarization with a magnetic field or magnetism with an electric one (for example, voltage-tunable spintronic devices, uncooled magnetic sensors and the long-searched magnetoelectric memory). A very promising novel material concept could be to make use of phase-change phenomena at structural instabilities of a multiferroic state. Indeed, large phase-change magnetoelectric response has been anticipated by a first-principles investigation of the perovskite BiFeO3–BiCoO3 solid solution, specifically at its morphotropic phase boundary between multiferroic polymorphs of rhombohedral and tetragonal symmetries. Here, we report a novel perovskite oxide that belongs to the BiFeO3–BiMnO3–PbTiO3 ternary system, chemically designed to present such multiferroic phase boundary with enhanced ferroelectricity and canted ferromagnetism, which shows distinctive room-temperature magnetoelectric responses.

(a) Zero-field-cooled (ZFC)/Field-cooled (FC) magnetization curves for the Bi0.68Pb0.32Fe0.655Mn0.025Ti0.32O3 ceramic under a dc magnetic field of 500Oe. The magnetic anomaly at 360K is associated with a spin-reorientation phenomenon (TSRO) within the Cc phase (Inset shows a schematic description of the proposed magnetic structure involved in the SRO in terms of ferromagnetic F and antiferromagnetic G components39, M stands for the ferromagnetic (FM) moment. Derivative curves highlights the Néel temperature (TNTet) at ∼100K of the P4mm phase. (b) Isothermal magnetization loop recorded at 300?K for the ceramic under study (ternary system) and that for the MPB composition of the binary system (0.675BiFeO3–0.325PbTiO3) for comparison.
