Fermi surface and field-induced Lifshitz transition in the antiferromagnet NbMnP exhibiting an anomalous Hall effect
Abstract
We performed Shubnikov--de Haas (SdH) oscillation measurements on the Q=0 antiferromagnet NbMnP, which exhibits a large anomalous Hall effect. The SdH frequencies observed in the low-field region up to 17.5~T are well described by first-principles band-structure calculations based on the B3g+B2u noncollinear magnetic structure determined by neutron diffraction. The effective masses are enhanced by approximately a factor of two relative to the calculated band masses. High-field measurements up to 41.5~T reveal a Lifshitz transition accompanied by a pronounced evolution of the SdH frequency spectrum. These results confirm that first-principles calculations provide a reliable tool for the development of functional antiferromagnetic materials, while also demonstrating that field-induced changes in the Fermi surface itself need to be taken into account in understanding their high-field magnetotransport properties.
