Tuning spin-orbit torques across the phase transition in VO/NiFe heterostructure
Jun-young Kim, Joel Cramer, Kyujoon Lee +9
The emergence of spin-orbit torques as a promising approach to energy-efficient magnetic switching has generated large interest in material systems with easily and fully tunable sp…
Faster chiral versus collinear magnetic order recovery after optical excitation revealed by femtosecond XUV scattering
Nico Kerber, Dmitriy Ksenzov, Frank Freimuth +11
While chiral spin structures stabilized by Dzyaloshinskii-Moriya interaction (DMI) are candidates as novel information carriers, their dynamics on the fs-ps timescale is little kno…
Impact of electromagnetic fields and heat on spin transport signals in YFeO
Joel Cramer, Lorenzo Baldrati, Andrew Ross +3
Exploring new strategies to perform magnon logic is a key requirement for the further development of magnon-based spintronics. In this work, we realize a three-terminal magnon tran…
Spin-dependent (inverse) spin Hall effect in CoFeB
Joel Cramer, Andrew Ross, Samridh Jaiswal +3
In ferromagnetic metals, the interconversion of spin and charge currents via the spin Hall effect and its inverse can depend on the angle between the ferromagnets magnetization and…
Spin transport across antiferromagnets induced by the spin Seebeck effect
Joel Cramer, Ulrike Ritzmann, Bo-Wen Dong +5
For prospective spintronics devices based on the propagation of pure spin currents, antiferromagnets are an interesting class of materials that potentially entail a number of advan…
