“…By refining the powder XRD data, the lattice parameters were determined to be a = 10.1508 (5) for an isolated Pr 3+ ion (3.58 µ B /Pr 3+ ), which is similar to the isostructural compounds, Pr 2 Pd 3 Ge 5 and Pr 2 Ni 3 Ge 5 . [5,6] We believe that such a large magnetic anisotropy as well as low M s value (≈ 1 µ B ) is probably due to the CEF effect. Figure 4(a) shows the dc magnetization divided by the magnetic field, in the low temperature region, and Fig.…”

“…RE 2 T M 3 X 5 (RE = Rare Earth elements, T M = Transition metal, and X = s − p metal, also known as '235 compounds') have been investigated for decades, because of their interesting magnetic [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] and superconducting properties. [8][9][10][11][12][13][14][15][16][17] Most magnetic 235 compounds exhibit a number of interesting properties, such as antiferromagnetic (AF) ordering, [2][3][4][5][6][7][8][9][10][11][12][13][14][15] metamagnetic phase transition (MMT), [5,6] high magnetoresistance (MR), [6,10] the crystalline electric field effect (CEF), [4][5][6][7][8...…”

[5,10,14] These interesting characteristics lend these compounds to studies of various novel ground states by the substitution of different elements in them.…”

“…For example, Ce 2 Rh 3 Ge 5 shows AF ordering with HF behavior, and Pr 2 Rh 3 Ge 5 shows HF behavior without any phase transition, while Pr 2 Pd 3 Ge 5 only shows AF ordering and MMT. [5,6,10] Moreover, superconductivity occurs when pressure is applied to Ce 2 Ni 3 Ge 5 , which has AF ordering, and re-entrant superconducting behavior is observed in Tm 2 Fe 3 Si 5 , where AF ordering affects the superconductivity. [13,14] Among the superconducting 235 compounds, Lu 2 Fe 3 Si 5 has been the focus of particularly intensive research because of its relatively high superconducting phase transition temperature of T c ∼ 6 K and its two-gap superconducting structure.…”

Magnetic and transport properties of Pr2Pd3Si5

“…Recently, we have reported our observation of magnetic order and heavy fermion behaviour in Pr 2 T 3 Ge 5 (T ¼ Ni, Pd, Rh) [5,6]. Both Pr 2 Ni 3 Ge 5 and Pr 2 Pd 3 Ge 5 order antiferromagnetically below 8.5 and 8.3 K, respectively, and exhibit anomalously high positive magnetoresistance despite the presence of field-induced metamagnetic transition.…”
