Event Details & Abstract: 

"New" materials are particularly important in condensed matter physics research. They either directly help advance technologies or provide a way address unresolved problems.  My talk will focus on our recent efforts to find new materials  that are potential for energy and spintronics applications. Due to the high cost and  the limited availability of the rare earth elements, which are the main constituents of the present day permanent magnets, it is necessary to find  a rare earth free version. Noncentrosymmetric magnets are a class of materials that  are likely to host  modulated magnetic structures such as skyrmions and solitons and are potential candidates for spintronics applications. In this talk,  I will discuss the hard ferromagnetic behavior of  Hf2Co11B, a competitive candidate for the non-rare earth permanent magnets and will present magnetic, thermal and transport properties of the noncentrosymmetric magnet Cr1/3NbS2, the sole known conductor  of the kind till date to host a soliton lattice.
