Dispersible SmCo5 nanoparticles with huge coercivity.
Ying Dong,Tianli Zhang,Zhengcai Xia,Hui Wang,Zhenhui Ma,Xin Liu,Wei Xia,J. M. D. Coey,J. M. D. Coey,Chengbao Jiang +9 more
TL;DR: The coercive mechanism is identified as nucleation and growth of 88 nm3 nucleation volumes in a low-anisotropy surface region about 15 nm thick and opens the prospect of new high-temperature magnet composites.

Prediction of the new efficient permanent magnet SmCoNiFe 3
Per Söderlind,Alexander Landa,Inka L. M. Locht,Daniel Åberg,Yaroslav Kvashnin,Manuel Pereiro,Markus Däne,Patrice E. A. Turchi,Vladimir Antropov,Olle Eriksson +9 more
TL;DR: In this paper, the authors proposed a new efficient permanent magnet, which is a development of the well-known ${\mathrm{SmCo}}_{5}$ prototype, and showed by means of first-principles electronic-structure calculations that the new magnet has very favorable magnetic properties.

Mitigating realistic noise in practical noisy intermediate-scale quantum devices
TL;DR: In this paper, a stochastic quantum error mitigation (QEM) method was proposed for noisy intermediate-scale quantum (NISQ) devices, where each computation process, being either digital or analog, is described by a continuous time evolution.
