Abstract Thermoelectric effects refer to the voltage generation from temperature gradients in condensed matter. Although various power generators are made from them, all the known effects, such as Seebeck effect, require macroscopic temperature gradi

Abstract Microactuators are essential for advances in micro-optics, ultrasonic transducers and microsensors, and there is a growing demand for miniaturization and improved power. Here we demonstrate the actuation of micromechanical structures based o

Topological materials such as topological insulators and Weyl/Dirac semimetals possess topologically protected surface states giving birth to various unique phenomena and functionaries. To investigate the surface transport phenomena toward possible a

Swift ion-beam irradiation affects physical properties of materials through radiation damages. In garnet ferrites, one of the best materials for magneto-optics, a heavy ion-beam creates a non-magnetic amorphous defect along the beam track. Because th

Chirality is breaking of mirror symmetry in matter. In the fields of biology and chemistry, this is particularly important because some of the essential molecules in life such as amino acids and DNA have chirality. It is a long-standing mystery how o

Chirality in a helimagnetic structure is determined by the sense of magnetic moment rotation. We found that the chiral information did not disappear even after the phase transition to the high-temperature ferromagnetic phase in a helimagnet MnP. The

We have investigated magnetic field effects on mechanical vibration of a magnetic microbridge made of ferrimagnetic insulator Y3Fe5O12 at room temperature. The mechanical resonance frequency of the bridge exhibits a steep change at the saturation mag

Mechanical resonance properties of a microcantilever made of a magnetic insulator have been investigated by laser-doppler vibrometry under DC magnetic fields and microwaves. At ferromagnetic resonance conditions, reduction of magnetization along the
