Similar to Er2Co17, the transition is accompanied by clear anomalies in the sound velocity. The observed 0.3% jump of the sound velocity at the transition is negative in Tm2Co17, whereas it is positive in Er analogue. In Tm compound, the transition is accompanied by a smooth minimum of 0.15x10-4 in longitudinal magnetostriction whereas in Er compound by a very sharp expansion of much larger magnitude (1.2x10-4). In the transverse mode, the effect in Tm compound looks as very broad minimum of low amplitude whereas in Er analogue as very sharp and large shrinkage. Thus, magnetoacoustics and magnetostriction support different nature of the field-induced transitions in Tm and Er compounds.
