“…1(e)], suggesting the presence of strong antiferromagnetic fluctuations above T N . The critical behavior of the MPE near the magnetic transition temperature could be a distinct feature from the magnetoelectric [11,12] and piezomagnetoelectric [14][15][16][17] responses in insulating magnets.…”

“…Furthermore, the MPE requires electric conduction, and is not observed in magnetic insulators that do not conduct electricity. This obviously differentiates the MPE from the piezomagnetoelectric effect reported in insulating magnets [14][15][16][17]. Second, the electric field is an intrinsic quantity in the piezoelectric effect, while the electric current is intrinsic in the MPE.…”

“…If the reduced crystal symmetry is noncentrosymmetric but nonpolar, spin-dependent piezoelectric effects are expected. A number of new spindependent piezoelectric effects have been explored in magnetic insulators, and generally termed piezomagnetoelectric effects [14][15][16][17].…”

We have experimentally studied a magnetopiezoelectric effect (MPE), i.e. dynamic distortion caused by ac electric currents, in the antiferromagnetic conductor CaMn 2 Bi 2 at low temperatures down to 77 K using laser Doppler vibrometry. When ac electric currents are applied to CaMn 2 Bi 2 , dynamic displacement signals which increase in proportion to the current amplitude are clearly observed at 77 K, but their magnitude and temperature dependence strongly depend on Joule heating effects caused by the applied electric currents. Especially, poor thermal contact of CaMn 2 Bi 2 samples to the sample holder produces second-harmonic displacement signals owing to thermal expansion due to the Joule heating, and tends to affect the temperature dependence of the MPE signals. In a measurement run without any heating effects, a sharp enhancement of the MPE signal is observed at the Néel temperature of CaMn 2 Bi 2 , which suggests that fluctuations of itinerant Mn moments near the Néel temperature play an important role in the MPE. We speculate that electric currents produce nonequilibrium antiferromagnetic moments via the antiferromagnetic Edelstein effect and the induced antiferromagnetic momemts enhance the MPE signal with the help of a large magneto-volume coupling near the Néel temperature. The MPE efficiency as a piezoelectric response reaches 300-500 pC/N at a maximum, which is comparable to high values of piezoelectric coefficients detected in the piezoelectric (ferroelectric) ceramics.

The main components of the tensor of the moduli of elasticity and the piezomodulus have been measured in monocrystals of the ferroborate HoFe3(BO3)4. The spin-dependent contributions to sound velocity, dielectric permeability, and piezoelectric response in the antiferromagnetic state were studied. The parameters of magnetoelectric and magnetoelastic interactions in an easy-plane magnetic-ordering phase have been defined. A phenomenological interpretation of observed effects is given.

The main elastic moduli and piezoelectric modulus have been measured in holmium alumoborate single crystals. The renormalization of the permittivity, piezoresponse, and sound velocities, driven by the nematic-like paramagnetic phase in the sample, is considered. A significant variability of the results is detected, which is caused, presumably, by the fact that, under the action of external fields, the motion trajectory of the nematic-like phase’s director depends on random defects of thermoelastic origin. It is shown that above 5 K, the temperature dependences of the studied parameters are well-described using holmium ion’s known ground multiplet spectrum, formed by the interaction with the crystal field. Changes in the C44-mode velocity in the sub-Kelvin temperature range are measured.
