Abstract null null We report anisotropic magnetocaloric effect and magnetoresistance in antiferromagnetic HoNiGe3 single crystal grown by Ge flux method. HoNiGe3 single crystal exhibits antiferromagnetic order and large magnetocrystalline anisotropy below the Neel temperature TN = 10.5 K. Meanwhile, with increasing the magnetic field, HoNiGe3 undergoes the spin-flip transition induced by the magnetic field along the a axis, while the spin-flop transition occurs for the field along the other orie...

Abstract The magnetic properties, magnetocaloric effect and magnetoresistance in ErNi single crystal have been investigated in detail. With decreasing temperature, ErNi single crystal undergoes two successive magnetic transitions: a paramagnetic to ferromagnetic transition at TC =11 K and a spin-reorientation transition at TSR =5 K. Meanwhile, a sharp field-induced metamagnetic transition is observed below the TC along the a axis. ErNi single crystal possesses a giant magnetocaloric effect aroun...

Abstract The topological Hall effect (THE) in general arises from the Berry phase acquired by conduction electrons moving in a noncoplanar spin textures such as skyrmions. In this paper, low-field induced THE is realized in a chiral-lattice B20-ordered Cr0.82Mn0.18Ge alloy. The maximum topological Hall resistivity of ρ xy T ≈ -0.048 μΩ cm at T = 10 K is achieved under a low magnetic field of about μ0H = 0.04 T, which reaches up to ∼20% of the anomalous Hall effect. Dip/peak anomalies are observe...

Abstract Solid-state refrigeration based on the magneto- or mechano-caloric effect, including elasto- and baro-caloric in ferroic phase transition materials is promising to replace the current vapor compression refrigeration in consideration of environmental-friendliness and energy-saving. However, both high driven field and small thermal changes in all of these caloric materials hinder the development of solid-state refrigeration. Here we report a giant baro-caloric effect near room temperature...

The effects of Cu substitution and annealing on the martensitic transformation behavior and magnetocaloric properties in all- d -metal Mn50Ni32– x Cu x Co8Ti10 ( x =1, 2) alloy ribbons have been mainly investigated. After the substitution, it is observed that the martensitic transformation temperature of the alloys, which was extremely sensitive to the Cu content, was reduced. Moreover, the ferromagnetism of austenite increased, increasing the magnetization difference across the martensitic tran...

We report the observation of the giant topological Hall effect near room temperature in a complex noncollinear ferromagnet NdMn2Ge2 single crystal. Three successive magnetic transitions are observed below 400 K, including a spin reorientation transition at TSR = 215 K. The complex noncollinear magnetic structures give rise to anomalous transport behaviors. When the current flows along the a axis and the magnetic field is applied along the c axis, the anomalous Hall effect is observed, which is f...

Abstract We report on giant rotating magnetocaloric effect in antiferromagnetic ErNi3Al9 single crystal with the trigonal structure. It is found that the signs of the magnetic entropy change for the field along the c axis and ab plane above the Neel temperature are opposite due to the crystal electric field. Therefore, the giant rotating magnetocaloric effect is obtained in ErNi3Al9 single crystal, and even larger than the conventional one. The maximum rotating magnetic entropy change and refrig...

Abstract In the present work, we reveal a novel finding, that is, self-assembled grain boundary precipitates for realizing the magnetic-field-induced metamagnetic transition by employing low melting point metal in materials. This strategy has been experimentally verified in a well-established ferrimagnetic compound Mn2Sb by doping the bismuth (Bi) element with a low melting point of just 271.3°C. Bi solidifies later than the Mn2(Sb,Bi) main phase in (Mn2Sb)1-xBix system (the melting point of ∼94...

Abstract The magnetic glass state has been proposed and studied in the ferromagnetic (FM) compounds undergoing the first-order FM-antiferromagnetic (AFM) transition. In this work, we have unequivocally demonstrated the occurrence of magnetic-glass-like transition during the field cooling process in the ferrimagnetic (FIM) Mn1.975Cr0.025Sb alloy showing a first-order FIM-AFM transition. The magnetic, resistance and relaxation studies characterize the formation of a nonergodic magnetic glass-like ...
