Internship

We are inviting applications for a 3-month internship project focusing on the micromagnetic modeling of write transducers for magnetic tape recording.

Background

Magnetic tape storage is used extensively for data archiving in data centers and by hyperscale cloud companies. Data is stored by writing magnetic transitions with a write transducer on a magnetic tape as it is streamed over a recording head. The write transducers are microfabricated electromagnets that are composed of a ferromagnetic yoke structure and a coil. To continue scaling the capacity of tape systems, it is critical to optimize the behavior of the write transducers. Micromagnetic modeling is a powerful tool that can be used to understand the complex magnetization dynamics that arises during write operations and to optimize the design of the writers. The theoretical background of micromagnetic simulations is a continuum theory, whose relevant length scale is small enough to resolve the magnetization domains and large enough to replace atomic spin distributions with a continuum magnetization field.

Description

The IBM tape research team recently developed a finite-element implementation of a micromagnetic model using variational principles. The magnetostatic problem is solved utilizing a combination of finite element and boundary element methods. The code is written in Python and parallelized for CPU-based high-performance computing. It features static, dynamic and hybrid solvers. The goals of the internship project are to further develop the model’s capabilities to simulate magnetization dynamics in the ferromagnetic core of a writer during write operations. The focus will be on understanding the formation and evolution of magnetic domains and the impact of geometric parameters on the write field.

Your profile

The internship is open to master’s or PhD students in electrical engineering, physics, materials science or a related field. The candidate should be familiar with concepts from magnetism and mechanics of materials. In addition, experience with numerical modeling as well as Python and HPC would be beneficial.

Diversity

IBM is committed to diversity at the workplace. With us you will find an open, multicultural environment. Excellent flexible working arrangements enable all genders to strike the desired balance between their professional development and their personal lives.
