Seminar DMONS – DCMI – Axis 5 presented by : Abhishake MONDAL

Abstract : 

The pursuit of smart multifunctional materials with stimuli-responsive magnetic and optical response has drawn escalating interest in both fundamental science and potential applications to switches, sensors, and intelligent devices.1 One of the appealing feature of such materials is the tunability of their physical property via chemistry, where the linking structure and physical properties can be modulated in practically infinite ways, which gives them an edge over the solid-state magnetic materials (Figure 1, a).2 The field of molecular bistable systems is rapidly budding towards utilizing these molecule-based magnetic materials in physics-driven and nanotechnology-driven fields (Figure 1, b).

Figure 1: a) Stimuli-responsive molecular bistable systems and b) Application areas where these systems are actively studied for developing devices

Here, I will briefly cover the exciting field of Molecular Magnetism and will specifically focus on three most important aspects of Molecular Magnetism being pursued in my laboratory i) Spin Crossover (SCO) materials3 ii) Metal-to-Metal Electron Transfer Systems (MMET)4 and iii) Single Molecule Magnets (SMM).5 Lastly, I shall discuss the application of these bistable systems in developing ring-resonator devices for Photonics Application, molecular break junctions and microelectromechanical systems.

Franco-Indian mini-workshop on two-dimensional ferroic materials and devices

This workshop is organised with the support of CEFIPRA, the French and Indian Ministries of Foreign Affairs and the ITI QMAT.

Around twenty oral presentations are scheduled.
Speakers have been selected from both academia and industry.
We will be discussing aspects relating to these materials, their fundamental properties and their applications, particularly in the field of memory and information echnologies.

For more information, you can refer to the attached flyer and the workshop website :

The workshop is open to all, and free of charge.
For organisational reasons, please let me know before 26 June noon of your participation by email ( dayen@unistra.fr ).

Workshop SWING

The goal of this workshop is to gather the French community working in the broad field of magnonics (i.e. physics and technologies of spin waves). This workshop will also serve as a scientific kick-off of the project SWING, whose focus is on applied magnonics, and which is part of the recently funded program PEPR Spin.
