Lay summary
This project concerns a range of fundamental questions in the field of magneto-electric multiferroics. Firstly, we will explore the electric field/temperature phase diagram of a thin film multiferroic with the goal to induce a magneto-electric quantum critical point. Secondly, we will investigate the nature of the excitations in magnetically-induced ferroelectrics, which can be of hybrid magneto-electric nature. This may help to understand whether such excitations can be used in the field of spintronics as wave-like excitations of a magnetic that carry and process information (magnonics), similarly as light waves in photonics. Thirdly, we will study multi-order quantum critical behaviour in organo-metallics, which present the simplest model materials to study multi-order quantum criticality. Finally, we will study a rare example of ferroelectric ferromagnetic material with the goal to identify the interactions that give rise to such behavior.

Abstract

We propose to work on a range of fundamental questions in the field of magneto-electric multiferroics. Firstly, we would like to explore the electric field/temperature phase diagram of a thin film multiferroic with the goal to induce a magneto-electric quantum critical point. Secondly, we propose to investigate the nature of the excitations in magnetically-induced ferroelectrics, which can be of hybrid magneto-electric nature. This may help to understand whether such excitations can be used in the field of spintronics as wave-like excitations of a magnetic that carry and process information (magnonics), similarly as light waves in photonics. Thirdly, we propose to study multi-order quantum critical behaviour in organo-metallics, which present the simplest model materials to study multi-order quantum criticality. Finally, we propose to study a rare example of ferroelectric ferromagnetic material with the goal to identify the interactions give rise to such behavior.
