A research article by Dr Tanmoy Chakrabarty, Assistant professor, Physics, SIAS titled, “Spin glass and complex magnetism in a high-entropy spinel oxide with five cations at both tetrahedral and octahedral sites” has been published in the “Applied Physics Letters”. In this publication, Dr Chakrabarty is one of the two corresponding authors.
In this work, the team has reported spin glass behavior and complex magnetic properties of a high-entropy spinel oxide with five cataions at tetrahedral and octahedral sites. They have carried out structural studies by XRD and SEM and studied magnetic properties using AC and DC magnetic measurements. The data from the AC magnetization confirms this material’s cluster spin glass state. Although spin glass behavior is a well reported phenomena among magnetic frustration, the novelty of this work is here it is first time observed in a high entropy oxide with 5 cations in both the tetrahedral and octahedral sites. The work highlights the potential of entropy-driven design in tailoring multifunctional materials for advanced applications.
