“…This phenomenon has been observed in several Eu-containing intermetallic and Zintl phases such as EuGa 4 , EuMn 2 P 2 , and EuSnP. 11,12,16 In those reports the authors suggested that there is a coexistent ferromagnetic ordering component that gives rise to this effect. 11,12,16 The vs T data were obtained with an applied field of 5 T. The shape of the susceptibility curve is no longer reminiscent of antiferromagnetism.…”

The shape of the susceptibility curve is no longer reminiscent of antiferromagnetism. Instead, the susceptibility (Figure 4) monotonically increases with decreasing temperature as with a ferromagnet.…”

A new rare earth metal Zintl phase, Eu 3 In 2 P 4 , was synthesized by utilizing a metal flux method. The compound crystallizes in the orthorhombic space group Pnnm with the cell parameters a ) 16.097(3) Å, b ) 6.6992(13) Å, c ) 4.2712(9) Å, and Z ) 2 (T ) 90(2) K, R1 ) 0.0159, wR2 ) 0.0418 for all data). It is isostructural to Sr 3 In 2 P 4 . The structure consists of tetrahedral dimers, [In 2 P 2 P 4/2 ] 6-, that form a one-dimensional chain along the c axis. Three europium atoms interact via a Eu−Eu distance of 3.7401(6) Å to form a straight line triplet. Single-crystal magnetic measurements show anisotropy at 30 K and a magnetic transition at 14.5 K. High-temperature data give a positive Weiss constant, which suggests ferromagnetism, while the shape of susceptibility curves (χ vs T) suggests antiferromagnetism. Heat capacity shows a magnetic transition at 14.5 K that is suppressed with field. This compound is a semiconductor according to the temperature-dependent resistivity measurements with a room-temperature resistivity of 0.005(1) Ω m and E g ) 0.452(4) eV. It shows negative magnetoresistance below the magnetic ordering temperature. The maximum magnetoresistance (∆F/F(H)) is 30% at 2 K with H ) 5 T.

“…The Eu ions are divalent and order magnetically at low temperature. Unusual magnetic properties [8][9][10][11][12][13] and colossal magneto-resistance (CMR) [14][15][16][17][18] have been observed. The compounds are typically antiferromagetic at low temperature [19,20] but often show a positive Weiss constant, which suggests ferromagnetic correlations in the paramagnetic region [11,12].…”
