Abstract Owing to geometrical frustration in the kagome lattice, Mn3Sn displays a 120° in-plane triangular antiferromagnetic order, a manifestation of exchange interaction within the Heisenberg model. Here, we show the formation of a tunable noncopl

Abstract Complex oxides are interesting materials where multiple physical properties and functionalities can be realized by integrating different elements in a single compound. However, owing to the chemical instability, not all the combinations of e

Abstract Applying a magnetic field to a solid changes its thermal-transport properties. Although such magneto-thermal-transport phenomena are usually small effects, giant magneto-thermal resistance has recently been observed in spintronic materials a

Abstract Bulk bismuth has a complex Landau spectrum. The small effective masses and the large g-factors are anisotropic. The chemical potential drifts at high magnetic fields. Moreover, twin boundaries further complexify the interpretation of the dat

Abstract Hysteretic behaviour accompanies any first-order phase transition, forming a basis for many applications. However, its quantitative understanding remains challenging, and even a qualitative understanding of pronounced hysteresis broadening a

Previous studies of magnetic Bose–Einstein condensates have been limited to magnetic materials with small spin numbers. Here the authors study the magnetic phase diagram of a S = 3/2 quantum antiferromagnet and show a double dome structure that is

Abstract Metamagnetic shape memory alloys (MMSMAs) are attractive functional materials owing to their unique properties such as magnetostrain, magnetoresistance, and the magnetocaloric effect caused by magnetic‐field‐induced transitions. However,
