“…The behaviors of these magnetization curves agree well with the results of previous works. 13,14,17,18) The inset in Fig. 2 shows the temperature dependence of the magnetic field B = 0.52 T divided by the magnetization for B ∥ a, B ∥ b, and B ∥ c. Above 50 K, these quantities obey the Curie-Weiss law, χ = C=(T − θ p ), where C is the Curie constant and θ p is the Weiss temperature.…”

“…9,10) Magnetization and neutron-diffraction measurements have shown that CrBtype RNi compounds have a collinear ferromagnetic structure, while FeB-type RNi compounds have non-collinear, canted magnetic structures. [11][12][13][14][15][16] Within the FeB-type RNi family, the compound HoNi undergoes a ferromagnetic transition at T C = 35 K, and reorientation of the magnetic moment occurs at T SR = 13 K. 13,14,17) In the temperature range between T C and T SR , the magnetic moments of single-crystalline HoNi have ferromagnetic and antiferromagnetic components along the a-and c-axes, respectively, as shown in Fig. 1.…”

We have studied the magnetocaloric effect (MCE) of single-crystal HoNi, which shows a ferromagnetic transition at TC = 35 K and a spin-reorientation transition at TSR = 13 K. Below TC, HoNi has ferromagnetic and antiferromagnetic components along the a- and c-axes, respectively. We find that the MCE in HoNi is highly anisotropic owing to the canted magnetic structure of this material. When a magnetic field is applied along the a- (B ∥ a) and b-axes (B ∥ b), the maximum isothermal magnetic-entropy change reaches 22.8 J K−1 kg−1 at 35 K and 18.8 J K−1 kg−1 at 13 K, respectively, when the magnetic field is increased from 0 to 5 T. On the other hand, for B ∥ c, is approximately three times smaller than those for B ∥ a and B ∥ b. In addition, the sign of depends on the temperature owing to the antiferromagnetic component along the c-axis and the existence of a metamagnetic transition.

“…In the temperature region below 15K, the resultant magnetic moments of HoNi incline 30 degrees from a-axis on the a-b plane, and approache a-axis with increasing temperature and coincide with a-axis between 15K and 37K [2]. The experiment of temperature dependence of heat capacity showed that there was the two transitions at 15K and 37K in HoNi [3]. Our purpose on this study is to control the magnetic interaction by applying pressure, and to clarify the magnetic property of HoNi.…”

The intermetallic compound HoNi single crystal has an orthorhombic FeB type crystal structure and magnetic orders at 15K (the temperature magnetic structure changes) and 37K (Curie temperature). We have measured the magnetic properties along c-axis under high pressure up to 1.5GPa with miniature high pressure cell and commercial MPMS. The magnetic transition temperature at 37K decreases 4 K/GPa with increasing pressure. The magnetic field observed the magnetic transition in the temperature range between 15K and 37K becomes lower with increasing pressure.

Specific heat measurements performed for Gd-Ni binary compounds with 1:2, 1:1 and 3:1 stoichiometry have revealed an additional contribution to the coefficient γ of the T -linear term of the low-temperature specific heat in comparison with that obtained for isostructural paramagnetic counterparts R-Ni (R = Y, Lu, La). This extra contribution γ is found to grow linearly with increasing Gd concentration from nearly zero for GdNi 5 up to γ ≈ 21.5 mJ g-at. −1 K −2 for Gd 3 Ni. To explain the appearance of γ and its dependence on the strength of the f-d exchange interaction in Gd-rich binary compounds with Ni a new mechanism enhancing the effective mass of conduction electrons is suggested. The increased γ value in Gd-containing compounds is attributed to spin fluctuations induced by the f-d exchange interaction in the hybridized 3d-5d electron subsystem.
