Dr. Md. Torikul Islam is currently serving as a Professor in the Physics Discipline at Khulna University, where he has been a faculty member since 2013. Prior to joining Khulna University, he held the position of Lecturer in the Department of Physics at Khulna University of Engineering & Technology (KUET) from June 2010 to February 2013.

Dr. Islam earned his B.Sc. (Hons.) and M.Sc. degrees in Physics from Jahangirnagar University. He was awarded an M.Phil. in Materials Science from KUET in 2013. Subsequently, he obtained his Ph.D. in Spintronics from the Hong Kong University of Science and Technology (HKUST) under the prestigious Hong Kong Ph.D. Fellowship Scheme in 2018.

From December 2022 to June 2025, Dr. Islam has been engaged as a Postdoctoral Research Fellow in the School of Materials Science and Engineering at Xi’an Jiaotong University (XJTU), China. During this period, he has also been involved in joint supervision of a Ph.D. student alongside Professor Min Tai.

Dr. Islam’s research interest focuses on the intersection of charge, spin, and magnon dynamics in nanostructured materials and devices. His current research focuses include:

  • Magnetization switching mechanisms driven by spin-transfer torque (STT), spin–orbit torque (SOT), and microwave chirped current pulses

  • Magnetic domain wall (DW) dynamics under magnon currents generated by thermal gradients

  • Spin current and magnetic field-induced DW motion in ferromagnetic and antiferromagnetic nanowires and devices

His contributions aim to advance the fundamental understanding of spintronic phenomena and pave the way for energy-efficient, high-speed next-generation memory and logic devices.

Recent findings on magnetization reversal by down chirp microwave field pulse Published in PRB Journal(https://journals.aps.org/prb/abstract/10.1103/PhysRevB.97.224412).


Animations show reversal of single domain of magnetic nanoparticle by Microwave chirp pulse 

 Magnetization takes longer time to reach the reversed state.

                                                          

However, with the applying of a proper down chirp microwave pulse, the magnetization is switched/reversed promptly.
