Research Areas

We give here a general description of research areas in which our group is active or has worked in the past.  Further down we give examples of specific research projects, which often span more than one of the research areas. We are interested in different fields of Material Science like- Multiferroics, Nanocrystalline Ferrites, DMS, Nanocrystalline Alloys and Colossal Magnetoresistance.

Nanostructures

In the last few years it has been possible to produce controllably in the laboratory structures of nano-meter scale, consisting of a relatively small (compared to a typical solid) number of atoms. These systems, referred to as 'nanostructures', exhibit interesting behavior and their size makes them ideal components for several types of applications, as for example in future electronic devices.

Magnetoresistance

Magnetoresistance is the property of a material to change the value of its electrical resistance when an external magnetic field is applied to it.
 

Perovskite

A perovskite structure is any material with the same type of crystal structure as calcium titanium oxide (CaTiO₃), known as the perovskite structure, or ^XIIA^2+VIB⁴⁺X²⁻₃ with the oxygen in the face centers.

.

Multiferroics

Multiferroics have been formally defined as materials that exhibit more than one primary ferroic order parameter simultaneously (i.e. in a single phase). Multi-ferroic composite materials are artificially designed and synthesized to have tailorable dielectric and magnetic properties such that capacitive and magnetic elements can be fabricated on the same material platform. Multi-ferroic composite serving as a multifunctional substrate for monolithic integration of capacitive and magnetic elements. Successful transfer of this technology would enable manufacturers of electronic products to shrink the size and weight of passive components in an electronic system, reduce the fabrication complexity, and potentially lower cost.
