Magnetic properties of a Tb3Ni single crystal

Magnetic structures and magnetic phase transitions in Ho3Co

“…At 1.5 K below T 1 additional second, third and highest harmonics appear. The observed magnetic neutron diffraction patterns have different propagation vectors than those reported in Dy 3 Co [6] and Tb 3 Co [7]. Note, this is the first observation of the incommensurability of the magnetic structure in the R 3 Co series.…”

Field-induced magnetic phase transitions and metastable states in Tb3Ni

“…The saturation of the resistivity observed in numerous R 3 T compounds was also ascribed to the short-range magnetic order persisting up to temperatures well above Néel temperature and s-d scattering mechanism [6,27]. The complex multi-component incommensurate magnetic structures observed in R 3 T with non-Kramers R ion apparently arise from the competition of exchange interactions of different types and lowsymmetry crystal electric field [6,[12][13][14][15].…”

“…Among the rare-earth intermetallic compounds, R 3 T (T = Co, Ni) compounds possess the highest content of rare-earth metal within the binary R − T systems and exhibit a rich variety of physical properties: unconventional superconductivity [7,8], charge density wave [9], giant magnetoresistance effect [10,11], multi-component magnetic structures exhibiting coexistence of commensurate and incommensurate propagation vectors [12,13], field-induced magnetic phase transitions [13][14][15][16] and giant magnetocaloric effect [17][18][19][20]. R 3 T compounds crystallize in a low-symmetry orthorhombic structure of the Fe 3 C type described with the space group P nma [21].…”

“…1 and Table I). The transition metal ions are located at the 4c sites between the layers and don't carry any magnetic moment [13,14,22], while spin-fluctuations in 3d or 4d band induced by f -d exchange may substantially affect macroscopic properties of the R 3 T compounds [23]. Particularly, spin-fluctuations were suggested to be responsible for an enhanced value of the T -linear specific heat coefficient (γ = 118 mJ mol −1 K −2 for Gd 3 Rh [23] and γ = 86 mJ mol −1 K −2 for Gd 3 Ni [24]) as well as for the tendency to saturation of the electrical resistivity in paramagnetic state [25,26].…”

High field magnetic properties in single crystal Nd3Co

“…[1][2][3][4][5] In our previous study 6 ͑of electrical resistivity, magnetic susceptibility and specific heat measurements͒, it was reported that Nd 3 Co has three magnetic transitions at low temperatures ͑spin reorientation temperatures T R1 ϭ8 K and T R2 ϭ13 K, and Néel temperature T N ϭ25 K͒. We also reported two field induced metamagnetic transitions along the a axis ͑transition fields of H a1 ϭ1.8 T and H a2 ϭ4.5 T͒ and one transition along the b axis ͑transition field H b ϭ1.9 T͒ below 7 T at 1.5 K. We proposed a canted magnetic structure to explain the complex magnetization process in Nd 3 Co. 6 However, a field of 7 T is not enough to achieve the saturation moment.…”
