M³ Lab & Research

Magnetism, Magnetic Materials & Magnetic Devices Lab

Labratory Information

This M3 Lab was started in 2008, leveraging the research expertise of the PI who had previously worked on magnetostrictive materials. It soon developed a research focus on nanoscale magnets with application to computing devices and more recently on neuromorphic computing. Three broad research themes pursued in our lab with an emphasis on current projects are described below.

Research Themes

Theme 1: Understanding magnetization dynamics in nanoscale magnets

(materials/physics)

A: “Straintronics”: Energy efficient switching of magnetization with strain (strain coupled multiferroics)

B: Voltage control (VCMA) of magnetization dynamics in nanomagnets and skyrmions

Theme 2: Nanomagnetic/spintronic devices for energy efficient and scalable non-volatile memory

(memory devices)

A: Switching nanomagents with resonant SAW and STT/SOT

B: Electric field switching of p-MTJs mediated by a skyrmion state

Theme 3: Nanomagnetic/spintronic devices for neuromorphic computing

(beyond Von Neumann computing)

A: Exploiting voltage controlled non-linear dynamics of spintronic oscillators for neuromorphic computing applications

B: Exploring low accuracy synaptic weights based on domain walls programmed by voltages for real time learning
