Postdoctoral Researcher (f/m/div)

We are seeking a highly motivated and talentedPostdoctoral Researcher (f / m / div)to join our dynamic research team in the field of spintronic materials and devices.

Topic : Strain Free All Heusler Alloy Junctions (SAHAJ) - Theoretical ResearchTo theoretically conduct individual and collaborative research projects, duties include modelling of ferrimagnetic materials and interpretation of research data use of appropriate research techniques and methods writing up of research results and dissemination through publications, seminar, and conference presentations to conduct research under the supervision of Prof.

Hirohata and to contribute to the production of research.Project overviewSpintronics is anticipated to replace current semiconductor-based memories and sensors based on fast-operating times ( ns) and low power consumption ( pJ per read / write operation).

The spintronic devices typically consist of a magnetoresistive junction with a free ferromagnet / oxide barrier or non-magnet / pinned ferromagnet trilayer and may suffer from edge-domain formation and leakage current through the barrier by further miniaturization ( 10 nm in cell diameter).

To avoid such obstacles, anti ferro magnetic spintronics has recently been developed by introducing spin-orbit torque which can reduce the power consumption by over two orders of magnitude but contain critical raw materials.

ln this transformative project, we aim to develop a ferri magnetic Heusler alloy film, in which the magne tic pro perties will be controlled by substituting the consti tuent element to achieve compensated ferri magnetism (effectively the same as anti ferro magnetism), sandwiched by weak and strong ferrimagnet in a single-step deposition.

This will be achieved based on our Heusler alloy database developed recently through existing collabo rations. The selected alloy(s) without using critical raw materials will be grown by dedicated combinatorial sputtering under low pressure and characterized by conventional structural and magnetic analysis as well as non-destructive imaging we have developed and syn chro tron-beam imaging at the Paul Scherrer lnstitute.

Such atomic engineering can offer a new way for material development for low-power electronics. The simplified growth process for a junction with out any interfacial scattering is adoptable for future spintronic devices as will be demonstrated using the 2OO mm wafer production line at IMEC by the end of this project.

Hence this proposed project will reveal both fundamental magnetic coupling in a ferrimagnetic alloy and atomic control of the alloy for new growth process, which can revolutionize spintronic device production.
