“…The values of transition temperatures observed here are in good agreement with the previous results. 25 As temperature decreases, the magnetization shows a decrease when it scans over 20 K. The ZFC curve show a characteristic similar to compensation effect in ferrimagnetic materials. All the above information indicates complex magnetic structure may exist and complex magnetic transition occurs.…”

“…Results show that the prepared compound is of single phase, crystallizing in the orthorhombic CrB-type structure (space group Cmcm) in agreement with the previous reports. 25,[38][39][40] The structure can be described as the stacking of triangular prims with rareearth atoms at the corners and the gallium atoms nearly at the center. R atoms and Ga atoms occupy two different 4c (0, y, 1/4) equivalent sites.…”

“…26,29,30,32,33 Analysis of Mössbauer spectra has shown that the rotation of the magnetic moments occurs in the ac-plane at low temperatures due to the competition between the exchange interaction and the interaction of the crystalline electric field in NdGa compound. 25,29 For polycrystalline NdGa compound, the applying of magnetic field will destroy the balance mentioned above. It is the most dramatic temperature zone that the magnetic order changes around T SR , thus noticeable magnetic entropy changes were observed around T SR .…”

Magnetic properties and magnetocaloric effect of HoCo 3 B 2 compound AIP Advances 8, 056432 (2018) The magnetic behavior and MCE property of NdGa compound were studied in detail. According to the temperature dependence of magnetization (M-T) curve at 0.01 T, two sharp changes were observed at 20 K (T SR ) and 42 K (T C ), respectively, corresponding to spin reorientation and FM-PM transition. Isothermal magnetization curves up to 5 T at different temperatures were measured and magnetic entropy change (∆S M ) was calculated based on M-H data. Temperature dependences of -∆S M for a field change of 0-2 T and 0-5 T show that there are two peaks on the curves corresponding to T SR and T C , respectively. The value of the two peaks is 6.4 J/kg K and 15.5 J/kg K for the field change of 0-5 T. Since the two peaks are close, the value of -∆S M in the temperature range between T SR and T C keeps a large value. The excellent MCE performance of NdGa compound benefits from the existence of two successive magnetic transitions. © 2018 Author (s)
