Current research programme -

 

1)      Enhancement of magnetization in nanoparticles -below AFM/FM ordering temperature- effect of particle size, Increase of Tc in comparison with bulk samples preferably close to room temperature for an applied orientedprogramme.

 

2)      Half metallicity in magnetic materials focusing on low Z elements.- Perovskitelike structures-metals excluding oxygen. AFM in metals unconventional magnets. Negative thermal expansion in AFM metals. Search for High curie temperature materials.

 

3)      Magneto structural transition in the vicinity of Martinsitic transition FM transition

 

4)      Composite magnets embedded with soft and hard magnetic phase for high energy product

 

5)      Search for large magneto resistance inspinel oxides, Magneto resistance in order-disordered transition, spin compensation temperatures and magnetic clusters inspinel ferrites -

 

6)      ordered moments in the absence of long range order- disordered magnets ( structural, quenched, chemical). Glassy magnetism
