“…5 This transition was also studied by specific heat and high field magnetization measurements and was associated with the iron spin reorientation from the easy 111 axis to a low-symmetry angular phase. 25,26 A slightly lower transition temperature of 14.5 K was reported in Ref. 25.…”

Symmetry analysis of the magnetic structures in TbIG and Tb:YIG at low temperature

“…When a spin reorientation phase transition temperature region exists, the space group must be a subgroup of the two groups at the ends [24] with the requirement that the two ends of the spin reorientation phase transitions are characterized by second order nature in the T-range (40-140 K) [18]. Despite the previous theoretical predictions [20] that the nature of the upper transition at the end of the spin reorientation phase transition <uuw> <111> might be first order like the transition observed at T SR = 14.5 K in DyIG [25,26], good agreement is found with another second order transition at T 2 = 135 K on Tb 0.26 Y 2.74 IG single crystal [27]. The monoclinic space group (C2/c) (Г 1g = A g ) [23] (table 2) …”

“…A and X are both restricted to non-magnetic cations as inclusion of magnetic cations on the A and X sites gives rise to additional magnetic phenomena [16][17][18][19][20][21]. The garnets crystallise in a cubic structure and contain three distinct cation sites based on the coordination with oxygen: dodecahedral occupied by Ln, octahedral occupied by A and tetrahedral occupied by X, Figure 1a.…”
