“…Back-scattered Laue patterns confirmed the single-crystal- High-field magnetoelasticity of Tm 2 Co 17 and comparison with Er 2 Co 17 line state of the sample. X-ray powder diffraction analysis confirmed single-phase state in the hexagonal crystal structure of the Th 2 Ni 17 type with lattice parameters a = = 828.6 pm, c = 809.4 pm in good agreement with those of crystal used in [6].…”

Acoustic properties (ultrasound velocity and attenuation) and magnetostriction were measured in pulsed fields up to 60 T applied along the c axis of Tm 2 Co 17 single crystal. Similar to Er 2 Co 17 , the transition in Tm 2 Co 17 is accompanied by clear anomalies in the sound velocity. The observed 0.3% jump of the sound velocity at the transition is negative in Tm 2 Co 17 , whereas it is positive in Er 2 Co 17 . The magnetostriction at the transition also differs very much from that in Er 2 Co 17 . In Tm 2 Co 17 , the transition is accompanied by a smooth minimum of 0.15•10 -4 in longitudinal magnetostriction whereas in Er 2 Co 17 by a very sharp expansion of much larger magnitude (1.2•10 -4 ). In the transverse mode, the effect in Tm 2 Co 17 looks as very broad minimum of low amplitude (< 0.1•10 -4 ) whereas in Er 2 Co 17 as very sharp and large shrinkage (2.6•10 -4). Thus, both the magnetoacoustics and magnetostriction are rather different in Tm 2 Co 17 and Er 2 Co 17 . This supports different nature of the field-induced transitions in these compounds.

“…The transition in Er 2 Co 17 is accompanied by pronounced anomalies in ultrasound velocity and magnetostriction [5]. We tried to measure these properties on the same crystal of Tm 2 Co 17 which was used for magnetization study in [6]. But that crystal occurred to be too small for the magnetoelastic measurements.…”

“…11 The value of H SF is much smaller compared to that found in ferrimagnets Ca 3 Co 2 O 6 , and Tm 2 Co 17 with H SF ∼ 4 T (Ref. 18) and 39 T, 19 respectively, revealing the much weaker spin-flop exchange interaction between spins in Cu 2 OSeO 3 .…”

“…In Ca 3 Co 2 O 6 and Tm 2 Co 17 , the spin flop occurs after a saturated plateau of magnetization. 19,20 Thus, to determine whether other metamagnetic states exist at higher magnetic fields, we used a pulsed-field magnet to perform a high-field magnetization Fig. 5.…”

dc and ac magnetization measurements were performed on single-crystal Cu 2 OSeO 3 under magnetic field (H) and hydrostatic pressure (P) conditions. Increasing H shifts the ferrimagnetic transition observed at T C ∼ 60 K to a higher-temperature region. Moreover, the T C increases linearly and magnetization is enhanced with P. Features of the ladder in the M-vs-H curve or the peak in the dM/dH-vs-H curve are observed at H SF ∼ 0.5 kOe, suggesting a competing ordered state under magnetic fields below T C . Remarkably, a second shoulder is observed at ∼1 kOe in the dM/dH-vs-H curve, revealing another metastable spin-ordered state in Cu 2 OSeO 3 . This state is retained and enhanced by applying pressure. As H rises to 55 T, no further slope changes in the M-H curve are observed. These magnetic properties indicate a complex spin orientation in the geometrically spin-frustrated system Cu 2 OSeO 3 .
