“…This increase in effective moment is attributed to the addition (or "stuffing") of magnetic transition metal atoms into the interstitial site of the structure with Fe possibly carrying a magnetic moment. The Weiss constants are also affected by Fe concentration and similar to the previously reported ErMn x Ga 3 (x < 0.15) and DyMn x Ga 3 (x < 0.45)[13,16]. ErFe 0.06(1) Ga 3 , ErFe 0.11(2) Ga 3 , and ErCo 0.06(2) Ga 3 order antiferromagnetically at T N ~ 5.2, 6.2, and 3.3 K, respectively, and slightly higher to the 2.antiferromagnetic ordering temperature of ErGa 3 .…”

“…The AuCu 3 -structure type is of particular interest in our goal to demonstrate how guest atoms in polyhedral subunits can affect the coupling strength of local magnetic moment with conduction electrons, thereby changing the physical properties [7]. Multiple reports indicate that the physical properties of materials are affected when atoms are inserted on to interstitial sites [8][9][10][11][12][13]. For instance, the hydrogenation of InPd 3 (ZrAl 3 -structure type) yields the hydride InPd 3 H 0.89 (AuCu 3 -structure type), where H occupies the octahedral interstitial site [8].…”

“…Although the Ln−Ln distances are increased relative to the parent compound (which would typically result in a lower ordering temperature), it was proposed that the conduction electrons of the transition metal can mediate Ln−Ln magnetic interactions in compounds with longer Ln−Ln contacts, thus resolving the potential conflict between theory and observation. A recent study has presented the crystal structure and magnetic properties of DyMn x Ga 3 (x ≤ 0.45) [13].…”

Structural stability and magnetic properties of LnM Ga3 (Ln = Ho, Er; M = Fe, Co; x< 0.2)

Single crystals of LnM x Ga 3 (Ln = Ho, Er; M = Fe, Co; x < 0.2) were grown from a Ga self-flux. The compounds crystallize in a "stuffed" variant of the AuCu 3 -structure type where Fe or Co partially occupies the body-centered position of the unit cell surrounded by six Ga atoms. The insertion of Fe or Co guest atoms into the AuCu 3 -structure type causes a structural change in the host material where chemical pressure is exerted on Ga-Ga contacts surrounding the filled octahedra. This in turn affects the stability of the AuCu 3 -structure type and the intrinsic properties of the materials. With increasing Ho−Ho distances of 4.2355(5), 4.2377(5), and 4.2441(3) Å, HoCo 0.16(2) Ga 3 , HoFe 0.11(1) Ga 3 , and HoFe 0.16(2) Ga 3 order antiferromagnetically with decreasing Néel temperatures of T N = 10.2, 7.2, and 6.5 K, respectively. ErCo 0.06(2) Ga 3 , ErFe 0.06(1) Ga 3 , and ErFe 0.11(2) Ga 3 order antiferromagnetically with Néel temperatures of T N = 3.3, 5.2, and 6.2 K. The magnetic properties are attributed to changes in the coupling strength of local magnetic moment with conduction electrons as a function of transition metal and rare earth.

Impact of Ge Doping on Structural and Magnetic Ordering in RMn_xGa₃ and R₄Mn_1–xGa_12–yGe_y (R = Tb, Dy; x ≤ 0.25, y ≈ 1.0–3.3)

Single crystals of RMn x Ga 3 and their new quaternary derivatives R 4 Mn 1−x Ga 12−y Ge y (R = Tb, Dy, x ≤ 0.25, y ≈ 1.0−3.3) were grown from a Ga flux. The compounds are derivatives of cubic RGa 3 phases, with Mn atoms filling the Ga 6 voids. RMn x Ga 3 formally adopts a cubic ABO 3 perovskite structure, in which the presence of Mn atoms results in a shift of the neighboring Ga atoms from their ideal position. A partial substitution of Ga by Ge leads to a higher Mn content, resulting in structural ordering of the latter and the formation of the superstructure phases R 4 Mn 1−x Ga 12−y Ge y , which can be formally described in the Y 4 PdGa 12 structure type. The presence of Mn vacancies, which was observed for R = Tb, and Ga/Ge mixing lead to a noticeable deviation from the idealized structure. The compounds contain two magnetic sublattices: the R sublattice, which orders antiferromagnetically near 20 K, and the Mn sublattice, which orders ferromagnetically at T C = 125−225 K with the Ge doping resulting in higher T C . The two sublattices are not independent, as the Mn sublattice induces partial ferromagnetic ordering of the rare earth atoms below T C , at least for the Ge-doped phases. Near T N , both magnetic susceptibility and heat capacity reveal complex behavior, indicating changes in magnetic structures below T N .
