A new way to generate electricity from waste heat: Using an antiferromagnet for solid devices
Forcing electrons to flow perpendicularly to a heat flow requires an external magnetic field—this is known as the Nernst effect. In a permanently magnetized material (a ferromagnet), an anomalous Nernst effect (ANE) exists that can generate electri.....»»

How heat waves are affecting Arctic phytoplankton
The basis of the marine food web in the Arctic, the phytoplankton, responds to heat waves much differently than to constantly elevated temperatures. This has been found by the first targeted experiments on the topic, which were recently conducted at.....»»
The observation of a Spin Berry curvature-enhanced orbital Zeeman effect in a kagome metal
In solid materials, magnetism generally originates from the alignment of electron spins. For instance, in the ferromagnet iron, the overall net magnetization is prompted by the alignment of spins in the same direction......»»
