Dr. Ying-Jiun Chen Honoured in “Rising Stars Collection”
Our congratulations go to Dr. Ying-Jiun Chen, ER-C-1/PGI-6, on her award from the journal “Applied Physics Letters”. Dr. Chen has been selected for inclusion in the prestigious “APL Rising Stars Collection 2024” for her outstanding work as lead author of the paper “Magnons in a two-dimensional Weyl magnet”. The collection showcases the best research work by early-career scientists and comprises only around 2% of the journal's total annual output.
The selection committee, consisting of members of the Editorial Advisory Board, chose Dr. Chen's work from a large number of excellent applications, according to the committee. The “APL Rising Stars Collection 2024” can be found on the AIP Publishing website.
The paper resulted from a collaboration with five other scientists from the Peter Grünberg Institute and a researcher from Taiwan. The team found that the presence of Weyl fermions in a two-dimensional magnet influences the magnon dispersion, leading to an unequal dispersion of magnons with opposite propagation direction. The discovery could have implications for the development of magnonics applications, such as magnetic storage media and magnetic sensors. The researchers hope that their results will pave the way to new approaches to magnon control and the development of innovative technologies.
Magnons are the elementary excitations of a magnetic material and play an important role in magnetic ordering and spin dynamics.
Weyl magnets are materials that exhibit a certain type of magnetic order and are characterised by the presence of Weyl fermions, massless quasiparticles that influence the magnetic order.
