“…Microdeformations do not influence the magnetization of these alloys (as one can see from Fig. 3) unlike the early obtained strong decrease of the temperatures of the magnetic phase transitions for the compositions with x = 0.6-0.9 [3]. This result confirms the supposition from Ref.…”

“…Polycrystalline ingots of the (TmxPr1-x)2Fe17 compounds with x = 0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.75, 0.8, 0.85, 0.9, 1 were prepared by induction melting [3]. The ingots were homogenized at 1293 K for two weeks and then quenched in water.…”

“…[4]. This alignment was performed at the temperatures T=270-272 K which are somewhat lower than the temperatures of the magnetic ordering of all the alloys except for the alloys with x=0.7-0.8 [3]. The X-ray diffraction patterns indicate a good magnetic alignment in the case of the single-phase compounds with x=0-0.3 (rhombohedral structure) and x=0.8-1 (hexagonal structure).…”

“…We take into account a real composition, Tm2Fe19.35, for the compounds with x=0.7-1, as it was obtained by means of neutron diffraction technique in Ref. [3]. The magnetic moments of the Pr, Tm and Fe ions were taken as 2.66 μB [1], 7 μB [2] and 2 μB, respectively.…”

“…Both the Pr2Fe17 and Tm2Fe17 binaries are characterized by FOMP (first order magnetization process) along the c-axis and in the basal plane, respectively. The magnetization anisotropy in Tm2Fe17 takes place at T = 4 K. Microdeformations in the (TmxPr1-x)2Fe17 alloys with x = 0.6-0.9 have been earlier detected by means of neutron diffraction at room temperature [3]. Feasibly, these microdeformations stipulate a nonmonotonous variation of the temperatures of magnetic phase transitions in the (TmxPr1-x)2Fe17 system.…”

The magnetization curves of magnetically aligned finely powdered samples of the (TmxPr1-x)2Fe17 compounds have been measured at 4 K. The easy magnetization axis is oriented in the basal plane or along the hexagonal axis for the compounds with x = 0-0.3 and 0.7-1, respectively. This is because of the absence of magnetic ordering in the Tm and Pr subsystems in these ranges, respectively, and because of competing anisotropy of the subsystems. For the compositions with x = 0.4-0.6, both rare-earth subsystems are magnetically ordered and the easy magnetization axis is oriented between the basal plane and the hexagonal axis. The critical fields of FOMPs decrease quickly as the Pr or Tm content decreases in the ranges 0-0.3 and 0.7-1, respectively. The magnetization anisotropy also diminishes as the Tm content becomes smaller than x = 0.7. No influence of the intrinsic microdeformations on the magnetization of the compounds was detected.
