Einstein–de Haas effect - Wikipedia
The Einstein–de Haas effect is a physical phenomenon in which a change in the magnetic moment of a free body causes this body to rotate. The effect is a consequence of the conservation of angular momentum. It is strong enough …
The ultrafast Einstein–de Haas effect - Nature
2019年1月2日 · Our results show that interaction with the lattice has an essential role in the process of ultrafast demagnetization in this system. Proposed mechanisms for ultrafast demagnetization...
Quantum Einstein-de Haas effect | Nature Communications
2016年4月29日 · Here we propose an experimental realization of an Einstein-de Haas experiment at the single-spin level based on a single-molecule magnet coupled to a nanomechanical resonator.
Einstein-de Haas effect: a bridge linking mechanics, magnetism, …
The Einstein-de Haas (EdH) effect is an interesting phenomenon linking mechanics and magnetism, in which changes in magnetization induce mechanical rotation. Despite being discovered more than a century ago, the EdH effect still shows crucial significance in modern science, particularly in the realms of spintronics and ultrafast magnetism.
Einstein–de Haas effect offers new insight into a puzzling magnetic ...
2019年1月15日 · More than 100 years ago, Albert Einstein and Wander Johannes de Haas discovered that when they used a magnetic field to flip the magnetic state of an iron bar dangling from a thread, the bar...

爱因斯坦－德哈斯效应（德文：Einstein-de-Haas-Effekt），又称作理查森效应（英文：Richardson effect，名从物理学家 欧文·理查森），是由 阿尔伯特·爱因斯坦 和万德尔·德哈斯在1910年代中期观测并描述的物理现象；此效应揭示了基本粒子的磁场、角动量和自旋之间的关系。 此现象所描述的是，一个依靠细线悬挂在导体 线圈 中的 铁磁体 （圆柱体并原先保持静止状 …
Quantum many-body dynamics of the Einstein--de Haas effect
2019年2月20日 · In 1915, Einstein and de Haas and Barnett demonstrated that changing the magnetization of a magnetic material results in mechanical rotation and vice versa. At the microscopic level, this effect governs the transfer between electron spin and orbital angular momentum, and lattice degrees of freedom, understanding which is key for molecular ...

2024年9月25日 · The Einstein-de Haas (EdH) effect is an interesting phenomenon linking mechanics and magnetism, in which changes in magnetization induce mechanical rotation. Despite being discovered more than a...
Einstein–de Haas effect at radio frequencies in and near magnetic ...
2020年8月10日 · The Einstein-de Haas (EdH) effect and its reciprocal, the Barnett effect, are fundamental to magnetism and uniquely yield measures of the ratio of magnetic moment to total angular momentum. These effects, small and generally difficult to observe, are enjoying a resurgence of interest as contemporary techniques enable new approaches to their study.
The original observation of the Einstein-de Haas effect was a landmark experiment in the early history of modern physics that illustrates the relationship between magnetism and angular momentum 1,2 .
